  11 //! # The Rust Core Library
  12 //!
  13 //! The Rust Core Library is the dependency-free[^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.
  18 //!
  19 //! [^free]: Strictly speaking, there are some symbols which are needed but
  20 //!          they aren't always necessary.
  21 //!
  22 //! The core library is *minimal*: it isn't even aware of heap allocation,
  23 //! nor does it provide concurrency or I/O. These things require
  24 //! platform integration, and this library is platform-agnostic.
  25 //!
  26 //! # How to use the core library
  27 //!
  28 // FIXME: Fill me in with more detail when the interface settles
  29 //! This library is built on the assumption of a few existing symbols:
  30 //!
  31 //! * `memcpy`, `memcmp`, `memset` - These are core memory routines which are
  32 //!   often generated by LLVM. Additionally, this library can make explicit
  33 //!   calls to these functions. Their signatures are the same as found in C.
  34 //!   These functions are often provided by the system libc, but can also be
  35 //!   provided by the [rlibc crate](https://crates.io/crates/rlibc).
  36 //!
  37 //! * `rust_begin_unwind` - This function takes three arguments, a
  38 //!   `fmt::Arguments`, a `&str`, and a `u32`. These three arguments dictate
  39 //!   the panic message, the file at which panic was invoked, and the line.
  40 //!   It is up to consumers of this core library to define this panic
  41 //!   function; it is only required to never return.
  42
  43 // Since libcore defines many fundamental lang items, all tests live in a
  44 // separate crate, libcoretest, to avoid bizarre issues.
