11 | //! # The Rust Core Library | |
12 | //! | |
92a42be0 | 13 | //! The Rust Core Library is the dependency-free[^free] foundation of [The |
1a4d82fc JJ |
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 | //! | |
92a42be0 SL |
19 | //! [^free]: Strictly speaking, there are some symbols which are needed but |
20 | //! they aren't always necessary. | |
21 | //! | |
1a4d82fc JJ |
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 | //! | |
1a4d82fc JJ |
26 | //! # How to use the core library |
27 | //! | |

28 | //! Please note that all of these details are currently not considered stable. |

30 | // FIXME: Fill me in with more detail when the interface settles |
31 | //! This library is built on the assumption of a few existing symbols: | |
32 | //! | |
33 | //! * `memcpy`, `memcmp`, `memset` - These are core memory routines which are | |
34 | //! often generated by LLVM. Additionally, this library can make explicit | |
35 | //! calls to these functions. Their signatures are the same as found in C. | |
36 | //! These functions are often provided by the system libc, but can also be | |
c34b1796 | 37 | //! provided by the [rlibc crate](https://crates.io/crates/rlibc). |
1a4d82fc | 38 | //! |
041b39d2 XL |
39 | //! * `rust_begin_panic` - This function takes four arguments, a |
40 | //! `fmt::Arguments`, a `&'static str`, and two `u32`'s. These four arguments | |
5bcae85e | 41 | //! dictate the panic message, the file at which panic was invoked, and the |
041b39d2 XL |
42 | //! line and column inside the file. It is up to consumers of this core |
43 | //! library to define this panic function; it is only required to never | |
44 | //! return. This requires a `lang` attribute named `panic_fmt`. | |
9e0c209e SL |
45 | //! |
46 | //! * `rust_eh_personality` - is used by the failure mechanisms of the | |
47 | //! compiler. This is often mapped to GCC's personality function, but crates | |
48 | //! which do not trigger a panic can be assured that this function is never | |
49 | //! called. The `lang` attribute is called `eh_personality`. | |
1a4d82fc JJ |
50 | |
51 | // Since libcore defines many fundamental lang items, all tests live in a | |
52 | // separate crate, libcoretest, to avoid bizarre issues. | |
