# The Rust standard library

The Rust standard library is a group of interrelated modules defining
the core language traits, operations on built-in data types, collections,
platform abstractions, the task scheduler, runtime support for language
features and other common functionality.

`std` 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`, `borrowed`).
Additionally, `std` 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`).

# Standard library injection and the Rust prelude

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

    extern mod std;

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

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

    use std::prelude::*;
