+/// The boolean type.
+///
+/// The `bool` represents a value, which could only be either [`true`] or [`false`]. If you cast
+/// a `bool` into an integer, [`true`] will be 1 and [`false`] will be 0.
+///
+/// # Basic usage
+///
+/// `bool` implements various traits, such as [`BitAnd`], [`BitOr`], [`Not`], etc.,
+/// which allow us to perform boolean operations using `&`, `|` and `!`.
+///
+/// [`if`] requires a `bool` value as its conditional. [`assert!`], which is an
+/// important macro in testing, checks whether an expression is [`true`] and panics
+/// if it isn't.
+///
+/// ```
+/// let bool_val = true & false | false;
+/// assert!(!bool_val);
+/// ```
+///
+/// [`true`]: ../std/keyword.true.html
+/// [`false`]: ../std/keyword.false.html
+/// [`BitAnd`]: ops::BitAnd
+/// [`BitOr`]: ops::BitOr
+/// [`Not`]: ops::Not
+/// [`if`]: ../std/keyword.if.html
+///
+/// # Examples
+///
+/// A trivial example of the usage of `bool`:
+///
+/// ```
+/// let praise_the_borrow_checker = true;
+///
+/// // using the `if` conditional
+/// if praise_the_borrow_checker {
+/// println!("oh, yeah!");
+/// } else {
+/// println!("what?!!");
+/// }
+///
+/// // ... or, a match pattern
+/// match praise_the_borrow_checker {
+/// true => println!("keep praising!"),
+/// false => println!("you should praise!"),
+/// }
+/// ```
+///
+/// Also, since `bool` implements the [`Copy`] trait, we don't
+/// have to worry about the move semantics (just like the integer and float primitives).
+///
+/// Now an example of `bool` cast to integer type:
+///
+/// ```
+/// assert_eq!(true as i32, 1);
+/// assert_eq!(false as i32, 0);
+/// ```
+#[stable(feature = "rust1", since = "1.0.0")]
+mod prim_bool {}
+
+#[doc(primitive = "never")]
+#[doc(alias = "!")]
+//
+/// The `!` type, also called "never".
+///
+/// `!` represents the type of computations which never resolve to any value at all. For example,
+/// the [`exit`] function `fn exit(code: i32) -> !` exits the process without ever returning, and
+/// so returns `!`.
+///
+/// `break`, `continue` and `return` expressions also have type `!`. For example we are allowed to
+/// write:
+///
+/// ```
+/// #![feature(never_type)]
+/// # fn foo() -> u32 {
+/// let x: ! = {
+/// return 123
+/// };
+/// # }
+/// ```
+///
+/// Although the `let` is pointless here, it illustrates the meaning of `!`. Since `x` is never
+/// assigned a value (because `return` returns from the entire function), `x` can be given type
+/// `!`. We could also replace `return 123` with a `panic!` or a never-ending `loop` and this code
+/// would still be valid.
+///
+/// A more realistic usage of `!` is in this code:
+///
+/// ```
+/// # fn get_a_number() -> Option<u32> { None }
+/// # loop {
+/// let num: u32 = match get_a_number() {
+/// Some(num) => num,
+/// None => break,
+/// };
+/// # }
+/// ```
+///
+/// Both match arms must produce values of type [`u32`], but since `break` never produces a value
+/// at all we know it can never produce a value which isn't a [`u32`]. This illustrates another
+/// behaviour of the `!` type - expressions with type `!` will coerce into any other type.
+///
+/// [`u32`]: prim@u32
+#[doc = concat!("[`exit`]: ", include_str!("../primitive_docs/process_exit.md"))]
+///
+/// # `!` and generics
+///
+/// ## Infallible errors
+///
+/// The main place you'll see `!` used explicitly is in generic code. Consider the [`FromStr`]
+/// trait:
+///
+/// ```
+/// trait FromStr: Sized {
+/// type Err;
+/// fn from_str(s: &str) -> Result<Self, Self::Err>;
+/// }
+/// ```
+///
+/// When implementing this trait for [`String`] we need to pick a type for [`Err`]. And since
+/// converting a string into a string will never result in an error, the appropriate type is `!`.
+/// (Currently the type actually used is an enum with no variants, though this is only because `!`
+/// was added to Rust at a later date and it may change in the future.) With an [`Err`] type of
+/// `!`, if we have to call [`String::from_str`] for some reason the result will be a
+/// [`Result<String, !>`] which we can unpack like this:
+///
+/// ```
+/// #![feature(exhaustive_patterns)]
+/// use std::str::FromStr;
+/// let Ok(s) = String::from_str("hello");
+/// ```
+///
+/// Since the [`Err`] variant contains a `!`, it can never occur. If the `exhaustive_patterns`
+/// feature is present this means we can exhaustively match on [`Result<T, !>`] by just taking the
+/// [`Ok`] variant. This illustrates another behaviour of `!` - it can be used to "delete" certain
+/// enum variants from generic types like `Result`.
+///
+/// ## Infinite loops
+///
+/// While [`Result<T, !>`] is very useful for removing errors, `!` can also be used to remove
+/// successes as well. If we think of [`Result<T, !>`] as "if this function returns, it has not
+/// errored," we get a very intuitive idea of [`Result<!, E>`] as well: if the function returns, it
+/// *has* errored.
+///
+/// For example, consider the case of a simple web server, which can be simplified to:
+///
+/// ```ignore (hypothetical-example)
+/// loop {
+/// let (client, request) = get_request().expect("disconnected");
+/// let response = request.process();
+/// response.send(client);
+/// }
+/// ```
+///
+/// Currently, this isn't ideal, because we simply panic whenever we fail to get a new connection.
+/// Instead, we'd like to keep track of this error, like this:
+///
+/// ```ignore (hypothetical-example)
+/// loop {
+/// match get_request() {
+/// Err(err) => break err,
+/// Ok((client, request)) => {
+/// let response = request.process();
+/// response.send(client);
+/// },
+/// }
+/// }
+/// ```
+///
+/// Now, when the server disconnects, we exit the loop with an error instead of panicking. While it
+/// might be intuitive to simply return the error, we might want to wrap it in a [`Result<!, E>`]
+/// instead:
+///
+/// ```ignore (hypothetical-example)
+/// fn server_loop() -> Result<!, ConnectionError> {
+/// loop {
+/// let (client, request) = get_request()?;
+/// let response = request.process();
+/// response.send(client);
+/// }
+/// }
+/// ```
+///
+/// Now, we can use `?` instead of `match`, and the return type makes a lot more sense: if the loop
+/// ever stops, it means that an error occurred. We don't even have to wrap the loop in an `Ok`
+/// because `!` coerces to `Result<!, ConnectionError>` automatically.
+///
+/// [`String::from_str`]: str::FromStr::from_str
+#[doc = concat!("[`String`]: ", include_str!("../primitive_docs/string_string.md"))]
+/// [`FromStr`]: str::FromStr
+///
+/// # `!` and traits
+///
+/// When writing your own traits, `!` should have an `impl` whenever there is an obvious `impl`
+/// which doesn't `panic!`. The reason is that functions returning an `impl Trait` where `!`
+/// does not have an `impl` of `Trait` cannot diverge as their only possible code path. In other
+/// words, they can't return `!` from every code path. As an example, this code doesn't compile:
+///
+/// ```compile_fail
+/// use std::ops::Add;
+///
+/// fn foo() -> impl Add<u32> {
+/// unimplemented!()
+/// }
+/// ```
+///
+/// But this code does:
+///
+/// ```
+/// use std::ops::Add;
+///
+/// fn foo() -> impl Add<u32> {
+/// if true {
+/// unimplemented!()
+/// } else {
+/// 0
+/// }
+/// }
+/// ```
+///
+/// The reason is that, in the first example, there are many possible types that `!` could coerce
+/// to, because many types implement `Add<u32>`. However, in the second example,
+/// the `else` branch returns a `0`, which the compiler infers from the return type to be of type
+/// `u32`. Since `u32` is a concrete type, `!` can and will be coerced to it. See issue [#36375]
+/// for more information on this quirk of `!`.
+///
+/// [#36375]: https://github.com/rust-lang/rust/issues/36375
+///
+/// As it turns out, though, most traits can have an `impl` for `!`. Take [`Debug`]
+/// for example:
+///
+/// ```
+/// #![feature(never_type)]
+/// # use std::fmt;
+/// # trait Debug {
+/// # fn fmt(&self, formatter: &mut fmt::Formatter<'_>) -> fmt::Result;
+/// # }
+/// impl Debug for ! {
+/// fn fmt(&self, formatter: &mut fmt::Formatter<'_>) -> fmt::Result {
+/// *self
+/// }
+/// }
+/// ```
+///
+/// Once again we're using `!`'s ability to coerce into any other type, in this case
+/// [`fmt::Result`]. Since this method takes a `&!` as an argument we know that it can never be
+/// called (because there is no value of type `!` for it to be called with). Writing `*self`
+/// essentially tells the compiler "We know that this code can never be run, so just treat the
+/// entire function body as having type [`fmt::Result`]". This pattern can be used a lot when
+/// implementing traits for `!`. Generally, any trait which only has methods which take a `self`
+/// parameter should have such an impl.
+///
+/// On the other hand, one trait which would not be appropriate to implement is [`Default`]:
+///
+/// ```
+/// trait Default {
+/// fn default() -> Self;
+/// }
+/// ```
+///
+/// Since `!` has no values, it has no default value either. It's true that we could write an
+/// `impl` for this which simply panics, but the same is true for any type (we could `impl
+/// Default` for (eg.) [`File`] by just making [`default()`] panic.)

+/// A character type.
+///
+/// The `char` type represents a single character. More specifically, since
+/// 'character' isn't a well-defined concept in Unicode, `char` is a '[Unicode
+/// scalar value]', which is similar to, but not the same as, a '[Unicode code
+/// point]'.
+///
+/// [Unicode scalar value]: https://www.unicode.org/glossary/#unicode_scalar_value
+/// [Unicode code point]: https://www.unicode.org/glossary/#code_point
+///
+/// This documentation describes a number of methods and trait implementations on the
+/// `char` type. For technical reasons, there is additional, separate
+/// documentation in [the `std::char` module](char/index.html) as well.
+///
+/// # Representation
+///
+/// `char` is always four bytes in size. This is a different representation than
+/// a given character would have as part of a [`String`]. For example:
+///
+/// ```
+/// let v = vec!['h', 'e', 'l', 'l', 'o'];
+///
+/// // five elements times four bytes for each element
+/// assert_eq!(20, v.len() * std::mem::size_of::<char>());
+///
+/// let s = String::from("hello");
+///
+/// // five elements times one byte per element
+/// assert_eq!(5, s.len() * std::mem::size_of::<u8>());
+/// ```
+///
+#[doc = concat!("[`String`]: ", include_str!("../primitive_docs/string_string.md"))]
+///
+/// As always, remember that a human intuition for 'character' might not map to
+/// Unicode's definitions. For example, despite looking similar, the 'é'
+/// character is one Unicode code point while 'é' is two Unicode code points:
+///
+/// ```
+/// let mut chars = "é".chars();
+/// // U+00e9: 'latin small letter e with acute'
+/// assert_eq!(Some('\u{00e9}'), chars.next());
+/// assert_eq!(None, chars.next());
+///
+/// let mut chars = "é".chars();
+/// // U+0065: 'latin small letter e'
+/// assert_eq!(Some('\u{0065}'), chars.next());
+/// // U+0301: 'combining acute accent'
+/// assert_eq!(Some('\u{0301}'), chars.next());
+/// assert_eq!(None, chars.next());
+/// ```
+///
+/// This means that the contents of the first string above _will_ fit into a
+/// `char` while the contents of the second string _will not_. Trying to create
+/// a `char` literal with the contents of the second string gives an error:
+///
+/// ```text
+/// error: character literal may only contain one codepoint: 'é'
+/// let c = 'é';
+/// ^^^
+/// ```
+///
+/// Another implication of the 4-byte fixed size of a `char` is that
+/// per-`char` processing can end up using a lot more memory:
+///
+/// ```
+/// let s = String::from("love: ❤️");
+/// let v: Vec<char> = s.chars().collect();
+///
+/// assert_eq!(12, std::mem::size_of_val(&s[..]));
+/// assert_eq!(32, std::mem::size_of_val(&v[..]));

+///
+/// *[See also the `std::ptr` module](ptr).*
+///
+/// Working with raw pointers in Rust is uncommon, typically limited to a few patterns.
+/// Raw pointers can be unaligned or [`null`]. However, when a raw pointer is
+/// dereferenced (using the `*` operator), it must be non-null and aligned.
+///
+/// Storing through a raw pointer using `*ptr = data` calls `drop` on the old value, so
+/// [`write`] must be used if the type has drop glue and memory is not already
+/// initialized - otherwise `drop` would be called on the uninitialized memory.
+///
+/// Use the [`null`] and [`null_mut`] functions to create null pointers, and the
+/// [`is_null`] method of the `*const T` and `*mut T` types to check for null.
+/// The `*const T` and `*mut T` types also define the [`offset`] method, for
+/// pointer math.
+///
+/// # Common ways to create raw pointers
+///
+/// ## 1. Coerce a reference (`&T`) or mutable reference (`&mut T`).
+///
+/// ```
+/// let my_num: i32 = 10;
+/// let my_num_ptr: *const i32 = &my_num;
+/// let mut my_speed: i32 = 88;
+/// let my_speed_ptr: *mut i32 = &mut my_speed;
+/// ```
+///
+/// To get a pointer to a boxed value, dereference the box:
+///
+/// ```
+/// let my_num: Box<i32> = Box::new(10);
+/// let my_num_ptr: *const i32 = &*my_num;
+/// let mut my_speed: Box<i32> = Box::new(88);
+/// let my_speed_ptr: *mut i32 = &mut *my_speed;
+/// ```
+///
+/// This does not take ownership of the original allocation
+/// and requires no resource management later,
+/// but you must not use the pointer after its lifetime.
+///
+/// ## 2. Consume a box (`Box<T>`).
+///
+/// The [`into_raw`] function consumes a box and returns
+/// the raw pointer. It doesn't destroy `T` or deallocate any memory.
+///
+/// ```
+/// let my_speed: Box<i32> = Box::new(88);
+/// let my_speed: *mut i32 = Box::into_raw(my_speed);
+///
+/// // By taking ownership of the original `Box<T>` though
+/// // we are obligated to put it together later to be destroyed.
+/// unsafe {
+/// drop(Box::from_raw(my_speed));
+/// }
+/// ```
+///
+/// Note that here the call to [`drop`] is for clarity - it indicates
+/// that we are done with the given value and it should be destroyed.
+///
+/// ## 3. Create it using `ptr::addr_of!`
+///
+/// Instead of coercing a reference to a raw pointer, you can use the macros
+/// [`ptr::addr_of!`] (for `*const T`) and [`ptr::addr_of_mut!`] (for `*mut T`).
+/// These macros allow you to create raw pointers to fields to which you cannot
+/// create a reference (without causing undefined behaviour), such as an
+/// unaligned field. This might be necessary if packed structs or uninitialized
+/// memory is involved.
+///
+/// ```
+/// #[derive(Debug, Default, Copy, Clone)]
+/// #[repr(C, packed)]
+/// struct S {
+/// aligned: u8,
+/// unaligned: u32,
+/// }
+/// let s = S::default();
+/// let p = std::ptr::addr_of!(s.unaligned); // not allowed with coercion
+/// ```
+///
+/// ## 4. Get it from C.
+///
+/// ```
+/// # #![feature(rustc_private)]

+///
+/// There are two syntactic forms for creating an array:

+/// * A repeat expression `[x; N]`, which produces an array with `N` copies of `x`.

+///
+/// Note that `[expr; 0]` is allowed, and produces an empty array.
+/// This will still evaluate `expr`, however, and immediately drop the resulting value, so

+/// Arrays of *any* size implement the following traits if the element type allows it:

+/// - [`Copy`]
+/// - [`Clone`]
+/// - [`Debug`]
+/// - [`IntoIterator`] (implemented for `[T; N]`, `&[T; N]` and `&mut [T; N]`)
+/// - [`PartialEq`], [`PartialOrd`], [`Eq`], [`Ord`]
+/// - [`Hash`]

+///
+/// Arrays of sizes from 0 to 32 (inclusive) implement the [`Default`] trait

+///
+/// Arrays coerce to [slices (`[T]`)][slice], so a slice method may be called on
+/// an array. Indeed, this provides most of the API for working with arrays.
+/// Slices have a dynamic size and do not coerce to arrays.
+///
+/// You can move elements out of an array with a [slice pattern]. If you want

+///
+/// # Examples
+///

+/// // This loop prints: 0 1 2

+/// print!("{} ", x);
+/// }
+/// ```
+///
+/// You can also iterate over reference to the array's elements:
+///
+/// ```
+/// let array: [i32; 3] = [0; 3];
+///
+/// for x in &array { }
+/// ```
+///
+/// You can use a [slice pattern] to move elements out of an array:

+/// [`IntoIterator`] by value. In the future, the behavior on the 2015 and 2018 edition
+/// might be made consistent to the behavior of later editions.
+///
+/// ```rust,edition2018

+/// // The `array_into_iter` lint suggests this change for future compatibility:
+/// for item in array.iter().enumerate() {
+/// let (i, x): (usize, &i32) = item;
+/// println!("array[{}] = {}", i, x);
+/// }
+///
+/// // You can explicitly iterate an array by value using

+/// }
+/// ```
+///
+/// Starting in the 2021 edition, `array.into_iter()` uses `IntoIterator` normally to iterate

+///
+/// ```rust,edition2021
+/// // Rust 2021:

+/// ```
+///
+/// Future language versions might start treating the `array.into_iter()`

+/// A 32-bit floating point type (specifically, the "binary32" type defined in IEEE 754-2008).
+///
+/// This type can represent a wide range of decimal numbers, like `3.5`, `27`,
+/// `-113.75`, `0.0078125`, `34359738368`, `0`, `-1`. So unlike integer types
+/// (such as `i32`), floating point types can represent non-integer numbers,
+/// too.
+///
+/// However, being able to represent this wide range of numbers comes at the
+/// cost of precision: floats can only represent some of the real numbers and
+/// calculation with floats round to a nearby representable number. For example,
+/// `5.0` and `1.0` can be exactly represented as `f32`, but `1.0 / 5.0` results
+/// in `0.20000000298023223876953125` since `0.2` cannot be exactly represented
+/// as `f32`. Note, however, that printing floats with `println` and friends will
+/// often discard insignificant digits: `println!("{}", 1.0f32 / 5.0f32)` will
+/// print `0.2`.
+///
+/// Additionally, `f32` can represent some special values:
+///
+/// - −0.0: IEEE 754 floating point numbers have a bit that indicates their sign, so −0.0 is a
+/// possible value. For comparison −0.0 = +0.0, but floating point operations can carry
+/// the sign bit through arithmetic operations. This means −0.0 × +0.0 produces −0.0 and
+/// a negative number rounded to a value smaller than a float can represent also produces −0.0.
+/// - [∞](#associatedconstant.INFINITY) and
+/// [−∞](#associatedconstant.NEG_INFINITY): these result from calculations
+/// like `1.0 / 0.0`.
+/// - [NaN (not a number)](#associatedconstant.NAN): this value results from
+/// calculations like `(-1.0).sqrt()`. NaN has some potentially unexpected
+/// behavior: it is unequal to any float, including itself! It is also neither
+/// smaller nor greater than any float, making it impossible to sort. Lastly,
+/// it is considered infectious as almost all calculations where one of the
+/// operands is NaN will also result in NaN.

+/// A reference represents a borrow of some owned value. You can get one by using the `&` or `&mut`
+/// operators on a value, or by using a [`ref`](../std/keyword.ref.html) or
+/// <code>[ref](../std/keyword.ref.html) [mut](../std/keyword.mut.html)</code> pattern.
+///
+/// For those familiar with pointers, a reference is just a pointer that is assumed to be
+/// aligned, not null, and pointing to memory containing a valid value of `T` - for example,
+/// <code>&[bool]</code> can only point to an allocation containing the integer values `1`
+/// ([`true`](../std/keyword.true.html)) or `0` ([`false`](../std/keyword.false.html)), but
+/// creating a <code>&[bool]</code> that points to an allocation containing
+/// the value `3` causes undefined behaviour.
+/// In fact, <code>[Option]\<&T></code> has the same memory representation as a
+/// nullable but aligned pointer, and can be passed across FFI boundaries as such.
+///
+/// In most cases, references can be used much like the original value. Field access, method
+/// calling, and indexing work the same (save for mutability rules, of course). In addition, the
+/// comparison operators transparently defer to the referent's implementation, allowing references
+/// to be compared the same as owned values.
+///
+/// References have a lifetime attached to them, which represents the scope for which the borrow is
+/// valid. A lifetime is said to "outlive" another one if its representative scope is as long or
+/// longer than the other. The `'static` lifetime is the longest lifetime, which represents the
+/// total life of the program. For example, string literals have a `'static` lifetime because the
+/// text data is embedded into the binary of the program, rather than in an allocation that needs
+/// to be dynamically managed.
+///
+/// `&mut T` references can be freely coerced into `&T` references with the same referent type, and
+/// references with longer lifetimes can be freely coerced into references with shorter ones.
+///
+/// Reference equality by address, instead of comparing the values pointed to, is accomplished via
+/// implicit reference-pointer coercion and raw pointer equality via [`ptr::eq`], while
+/// [`PartialEq`] compares values.

+/// pointers, make your type [`Option<fn()>`](core::option#options-and-pointers-nullable-pointers)
+/// with your required signature.
+///
+/// ### Safety
+///
+/// Plain function pointers are obtained by casting either plain functions, or closures that don't
+/// capture an environment:
+///
+/// ```
+/// fn add_one(x: usize) -> usize {
+/// x + 1
+/// }
+///
+/// let ptr: fn(usize) -> usize = add_one;
+/// assert_eq!(ptr(5), 6);
+///
+/// let clos: fn(usize) -> usize = |x| x + 5;
+/// assert_eq!(clos(5), 10);
+/// ```
+///
+/// In addition to varying based on their signature, function pointers come in two flavors: safe
+/// and unsafe. Plain `fn()` function pointers can only point to safe functions,
+/// while `unsafe fn()` function pointers can point to safe or unsafe functions.
+///
+/// ```
+/// fn add_one(x: usize) -> usize {
+/// x + 1
+/// }
+///
+/// unsafe fn add_one_unsafely(x: usize) -> usize {
+/// x + 1
+/// }
+///
+/// let safe_ptr: fn(usize) -> usize = add_one;
+///
+/// //ERROR: mismatched types: expected normal fn, found unsafe fn
+/// //let bad_ptr: fn(usize) -> usize = add_one_unsafely;
+///
+/// let unsafe_ptr: unsafe fn(usize) -> usize = add_one_unsafely;
+/// let really_safe_ptr: unsafe fn(usize) -> usize = add_one;
+/// ```
+///
+/// ### ABI
+///
+/// On top of that, function pointers can vary based on what ABI they use. This
+/// is achieved by adding the `extern` keyword before the type, followed by the
+/// ABI in question. The default ABI is "Rust", i.e., `fn()` is the exact same
+/// type as `extern "Rust" fn()`. A pointer to a function with C ABI would have
+/// type `extern "C" fn()`.
+///
+/// `extern "ABI" { ... }` blocks declare functions with ABI "ABI". The default
+/// here is "C", i.e., functions declared in an `extern {...}` block have "C"
+/// ABI.
+///
+/// For more information and a list of supported ABIs, see [the nomicon's
+/// section on foreign calling conventions][nomicon-abi].
+///
+/// [nomicon-abi]: ../nomicon/ffi.html#foreign-calling-conventions
+///
+/// ### Variadic functions
+///
+/// Extern function declarations with the "C" or "cdecl" ABIs can also be *variadic*, allowing them
+/// to be called with a variable number of arguments. Normal Rust functions, even those with an
+/// `extern "ABI"`, cannot be variadic. For more information, see [the nomicon's section on
+/// variadic functions][nomicon-variadic].
+///
+/// [nomicon-variadic]: ../nomicon/ffi.html#variadic-functions
+///
+/// ### Creating function pointers
+///
+/// When `bar` is the name of a function, then the expression `bar` is *not* a
+/// function pointer. Rather, it denotes a value of an unnameable type that
+/// uniquely identifies the function `bar`. The value is zero-sized because the
+/// type already identifies the function. This has the advantage that "calling"
+/// the value (it implements the `Fn*` traits) does not require dynamic
+/// dispatch.
+///
+/// This zero-sized type *coerces* to a regular function pointer. For example:
+///
+/// ```rust
+/// use std::mem;
+///
+/// fn bar(x: i32) {}
+///
+/// let not_bar_ptr = bar; // `not_bar_ptr` is zero-sized, uniquely identifying `bar`
+/// assert_eq!(mem::size_of_val(¬_bar_ptr), 0);
+///
+/// let bar_ptr: fn(i32) = not_bar_ptr; // force coercion to function pointer
+/// assert_eq!(mem::size_of_val(&bar_ptr), mem::size_of::<usize>());
+///
+/// let footgun = &bar; // this is a shared reference to the zero-sized type identifying `bar`
+/// ```
+///
+/// The last line shows that `&bar` is not a function pointer either. Rather, it
+/// is a reference to the function-specific ZST. `&bar` is basically never what you
+/// want when `bar` is a function.
+///
+/// ### Traits
+///
+/// Function pointers implement the following traits:
+///
+/// * [`Clone`]
+/// * [`PartialEq`]
+/// * [`Eq`]
+/// * [`PartialOrd`]
+/// * [`Ord`]
+/// * [`Hash`]
+/// * [`Pointer`]
+/// * [`Debug`]
+///
+/// [`Hash`]: hash::Hash
+/// [`Pointer`]: fmt::Pointer
+///
+/// Due to a temporary restriction in Rust's type system, these traits are only implemented on
+/// functions that take 12 arguments or less, with the `"Rust"` and `"C"` ABIs. In the future, this
+/// may change.
+///
+/// In addition, function pointers of *any* signature, ABI, or safety are [`Copy`], and all *safe*
+/// function pointers implement [`Fn`], [`FnMut`], and [`FnOnce`]. This works because these traits
+/// are specially known to the compiler.

As a consequence, you should only use GNU assembler **numeric** [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.
-Moreover, on x86 when using the default intel syntax, due to [an llvm bug], you shouldn't use labels exclusively made of `0` and `1` digits, e.g. `0`, `11` or `101010`, as they may end up being interpreted as binary values. Using `option(att_syntax)` will avoid any ambiguity, but that affects the syntax of the _entire_ `asm!` block.
