11 //! # The Rust Core Library
13 //! The Rust Core Library is the dependency-free foundation of [The
14 //! Rust Standard Library](../std/index.html). It is the portable glue
15 //! between the language and its libraries, defining the intrinsic and
16 //! primitive building blocks of all Rust code. It links to no
17 //! upstream libraries, no system libraries, and no libc.
19 //! The core library is *minimal*: it isn't even aware of heap allocation,
20 //! nor does it provide concurrency or I/O. These things require
21 //! platform integration, and this library is platform-agnostic.
23 //! *It is not recommended to use the core library*. The stable
24 //! functionality of libcore is reexported from the
25 //! [standard library](../std/index.html). The composition of this library is
26 //! subject to change over time; only the interface exposed through libstd is
27 //! intended to be stable.
29 //! # How to use the core library
31 // FIXME: Fill me in with more detail when the interface settles
32 //! This library is built on the assumption of a few existing symbols:
34 //! * `memcpy`, `memcmp`, `memset` - These are core memory routines which are
35 //! often generated by LLVM. Additionally, this library can make explicit
36 //! calls to these functions. Their signatures are the same as found in C.
37 //! These functions are often provided by the system libc, but can also be
38 //! provided by `librlibc` which is distributed with the standard rust
41 //! * `rust_begin_unwind` - This function takes three arguments, a
42 //! `fmt::Arguments`, a `&str`, and a `uint`. These three arguments dictate
43 //! the panic message, the file at which panic was invoked, and the line.
44 //! It is up to consumers of this core library to define this panic
45 //! function; it is only required to never return.
47 // Since libcore defines many fundamental lang items, all tests live in a
48 // separate crate, libcoretest, to avoid bizarre issues.
