# The Rust core library

The Rust core library provides runtime features required by the language,
including the task scheduler and memory allocators, as well as library
support for Rust built-in types, platform abstractions, and other commonly
used features.

`core` includes modules corresponding to each of the integer types, each of
the floating point types, the `bool` type, tuples, characters, strings
(`str`), vectors (`vec`), managed boxes (`managed`), owned boxes (`owned`),
and unsafe and borrowed pointers (`ptr`).  Additionally, `core` provides
pervasive types (`option` and `result`), task creation and communication
primitives (`task`, `comm`), platform abstractions (`os` and `path`), basic
I/O abstractions (`io`), common traits (`kinds`, `ops`, `cmp`, `num`,
`to_str`), and complete bindings to the C standard library (`libc`).

# Core injection and the Rust prelude

`core` is imported at the topmost level of every crate by default, as
if the first line of each crate was

    extern mod core;

This means that the contents of core can be accessed from from any context
with the `core::` path prefix, as in `use core::vec`, `use core::task::spawn`,
etc.

Additionally, `core` contains a `prelude` module that reexports many of the
most common core modules, types and traits. The contents of the prelude are
imported into every *module* by default.  Implicitly, all modules behave as if
they contained the following prologue:

    use core::prelude::*;
