11 | //! # The Rust Core Library | |
12 | //! | |
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. | |
18 | //! | |
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. | |
22 | //! | |
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. | |
28 | //! | |
29 | //! # How to use the core library | |
30 | //! | |
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: | |
33 | //! | |
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 | |
c34b1796 | 38 | //! provided by the [rlibc crate](https://crates.io/crates/rlibc). |
1a4d82fc JJ |
39 | //! |
40 | //! * `rust_begin_unwind` - This function takes three arguments, a | |
9346a6ac | 41 | //! `fmt::Arguments`, a `&str`, and a `u32`. These three arguments dictate |
1a4d82fc JJ |
42 | //! the panic message, the file at which panic was invoked, and the line. |
43 | //! It is up to consumers of this core library to define this panic | |
44 | //! function; it is only required to never return. | |
45 | ||
46 | // Since libcore defines many fundamental lang items, all tests live in a | |
47 | // separate crate, libcoretest, to avoid bizarre issues. | |
