Constant values must not have destructors, and otherwise permit most forms of
data. Constants may refer to the address of other constants, in which case the
-address will have the `static` lifetime. The compiler is, however, still at
-liberty to translate the constant many times, so the address referred to may not
-be stable.
+address will have elided lifetimes where applicable, otherwise – in most cases –
+defaulting to the `static` lifetime. (See below on [static lifetime elision].)
+The compiler is, however, still at liberty to translate the constant many times,
+so the address referred to may not be stable.
+
+[static lifetime elision]: #static-lifetime-elision
Constants must be explicitly typed. The type may be `bool`, `char`, a number, or
a type derived from those primitive types. The derived types are references with
the `static` lifetime, fixed-size arrays, tuples, enum variants, and structs.
-```
+```rust
const BIT1: u32 = 1 << 0;
const BIT2: u32 = 1 << 1;
};
```
+
+
### Static items
A *static item* is similar to a *constant*, except that it represents a precise
Mutable statics are still very useful, however. They can be used with C
libraries and can also be bound from C libraries (in an `extern` block).
-```
+```rust
# fn atomic_add(_: &mut u32, _: u32) -> u32 { 2 }
static mut LEVELS: u32 = 0;
Mutable statics have the same restrictions as normal statics, except that the
type of the value is not required to ascribe to `Sync`.
+#### `'static` lifetime elision
+
+[Unstable] Both constant and static declarations of reference types have
+*implicit* `'static` lifetimes unless an explicit lifetime is specified. As
+such, the constant declarations involving `'static` above may be written
+without the lifetimes. Returning to our previous example:
+
+```rust
+# #![feature(static_in_const)]
+const BIT1: u32 = 1 << 0;
+const BIT2: u32 = 1 << 1;
+
+const BITS: [u32; 2] = [BIT1, BIT2];
+const STRING: &str = "bitstring";
+
+struct BitsNStrings<'a> {
+ mybits: [u32; 2],
+ mystring: &'a str,
+}
+
+const BITS_N_STRINGS: BitsNStrings = BitsNStrings {
+ mybits: BITS,
+ mystring: STRING,
+};
+```
+
+Note that if the `static` or `const` items include function or closure
+references, which themselves include references, the compiler will first try the
+standard elision rules ([see discussion in the nomicon][elision-nomicon]). If it
+is unable to resolve the lifetimes by its usual rules, it will default to using
+the `'static` lifetime. By way of example:
+
+[elision-nomicon]: https://doc.rust-lang.org/nomicon/lifetime-elision.html
+
+```rust,ignore
+// Resolved as `fn<'a>(&'a str) -> &'a str`.
+const RESOLVED_SINGLE: fn(&str) -> &str = ..
+
+// Resolved as `Fn<'a, 'b, 'c>(&'a Foo, &'b Bar, &'c Baz) -> usize`.
+const RESOLVED_MULTIPLE: Fn(&Foo, &Bar, &Baz) -> usize = ..
+
+// There is insufficient information to bound the return reference lifetime
+// relative to the argument lifetimes, so the signature is resolved as
+// `Fn(&'static Foo, &'static Bar) -> &'static Baz`.
+const RESOLVED_STATIC: Fn(&Foo, &Bar) -> &Baz = ..
+```
+
### Traits
A _trait_ describes an abstract interface that types can
### Miscellaneous attributes
-- `deprecated` - mark the item as deprecated; the full attribute is `#[deprecated(since = "crate version", note = "...")`, where both arguments are optional.
+- `deprecated` - mark the item as deprecated; the full attribute is
+ `#[deprecated(since = "crate version", note = "...")`, where both arguments
+ are optional.
- `export_name` - on statics and functions, this determines the name of the
exported symbol.
- `link_section` - on statics and functions, this specifies the section of the
into a Rust program. This capability, especially the signature for the
annotated function, is subject to change.
-* `static_in_const` - Enables lifetime elision with a `'static` default for
- `const` and `static` item declarations.
-
* `thread_local` - The usage of the `#[thread_local]` attribute is experimental
and should be seen as unstable. This attribute is used to
declare a `static` as being unique per-thread leveraging
