|
||
<p>The Rust Standard Library is the foundation of portable Rust software, a
|
||
set of minimal and battle-tested shared abstractions for the <a href="https://crates.io">broader Rust
|
||
ecosystem</a>. It offers core types, like <a href="vec/struct.Vec.html" title="struct std::vec::Vec"><code>Vec<T></code></a> and
|
||
<a href="option/enum.Option.html" title="enum std::option::Option"><code>Option<T></code></a>, library-defined <a href="#primitives">operations on language
|
||
primitives</a>, <a href="#macros">standard macros</a>, <a href="io/index.html" title="mod std::io">I/O</a> and
|
||
<a href="thread/index.html" title="mod std::thread">multithreading</a>, among <a href="#what-is-in-the-standard-library-documentation">many other things</a>.</p>
|
||
<p><code>std</code> is available to all Rust crates by default. Therefore, the
|
||
standard library can be accessed in <a href="../book/ch07-02-defining-modules-to-control-scope-and-privacy.html"><code>use</code></a> statements through the path
|
||
<code>std</code>, as in <a href="env/index.html"><code>use std::env</code></a>.</p>

||
<h2 id="how-to-read-this-documentation"><a class="doc-anchor" href="#how-to-read-this-documentation">§</a>How to read this documentation</h2>
|
||
<p>If you already know the name of what you are looking for, the fastest way to
|
||
find it is to use the <a href="#" onclick="window.searchState.focus();">search
|
||
button</a> at the top of the page.</p>
|
||
<p>Otherwise, you may want to jump to one of these useful sections:</p>
|
||
<ul>
|
||
<li><a href="#modules"><code>std::*</code> modules</a></li>
|
||
<li><a href="#primitives">Primitive types</a></li>
|
||
<li><a href="#macros">Standard macros</a></li>
|
||
<li><a href="prelude/index.html" title="mod std::prelude">The Rust Prelude</a></li>
|
||
</ul>
|
||
<p>If this is your first time, the documentation for the standard library is
|
||
written to be casually perused. Clicking on interesting things should
|
||
generally lead you to interesting places. Still, there are important bits
|
||
you don’t want to miss, so read on for a tour of the standard library and
|
||
its documentation!</p>
|
||
<p>Once you are familiar with the contents of the standard library you may
|
||
begin to find the verbosity of the prose distracting. At this stage in your
|
||
development you may want to press the
|
||
“<svg style="width:0.75rem;height:0.75rem" viewBox="0 0 12 12" stroke="currentColor" fill="none"><path d="M2,2l4,4l4,-4M2,6l4,4l4,-4"></path></svg> Summary”
|
||
button near the top of the page to collapse it into a more skimmable view.</p>
|
||
<p>While you are looking at the top of the page, also notice the
|
||
“Source” link. Rust’s API documentation comes with the source
|
||
code and you are encouraged to read it. The standard library source is
|
||
generally high quality and a peek behind the curtains is
|
||
often enlightening.</p>
|
||
<h2 id="what-is-in-the-standard-library-documentation"><a class="doc-anchor" href="#what-is-in-the-standard-library-documentation">§</a>What is in the standard library documentation?</h2>
|
||
<p>First of all, The Rust Standard Library is divided into a number of focused
|
||
modules, <a href="#modules">all listed further down this page</a>. These modules are
|
||
the bedrock upon which all of Rust is forged, and they have mighty names
|
||
like <a href="slice/index.html" title="mod std::slice"><code>std::slice</code></a> and <a href="cmp/index.html" title="mod std::cmp"><code>std::cmp</code></a>. Modules’ documentation typically
|
||
includes an overview of the module along with examples, and are a smart
|
||
place to start familiarizing yourself with the library.</p>
|
||
<p>Second, implicit methods on <a href="../book/ch03-02-data-types.html">primitive types</a> are documented here. This can
|
||
be a source of confusion for two reasons:</p>
|
||
<ol>
|
||
<li>While primitives are implemented by the compiler, the standard library
|
||
implements methods directly on the primitive types (and it is the only
|
||
library that does so), which are <a href="#primitives">documented in the section on
|
||
primitives</a>.</li>
|
||
<li>The standard library exports many modules <em>with the same name as
|
||
primitive types</em>. These define additional items related to the primitive
|
||
type, but not the all-important methods.</li>
|
||
</ol>
|
||
<p>So for example there is a <a href="primitive.char.html" title="primitive char">page for the primitive type
|
||
<code>char</code></a> that lists all the methods that can be called on
|
||
characters (very useful), and there is a <a href="char/index.html" title="mod std::char">page for the module
|
||
<code>std::char</code></a> that documents iterator and error types created by these methods
|
||
(rarely useful).</p>
|
||
<p>Note the documentation for the primitives <a href="primitive.str.html" title="primitive str"><code>str</code></a> and <a href="primitive.slice.html" title="primitive slice"><code>[T]</code></a> (also
|
||
called ‘slice’). Many method calls on <a href="string/struct.String.html" title="struct std::string::String"><code>String</code></a> and <a href="vec/struct.Vec.html" title="struct std::vec::Vec"><code>Vec<T></code></a> are actually
|
||
calls to methods on <a href="primitive.str.html" title="primitive str"><code>str</code></a> and <a href="primitive.slice.html" title="primitive slice"><code>[T]</code></a> respectively, via <a href="../book/ch15-02-deref.html#implicit-deref-coercions-with-functions-and-methods">deref
|
||
coercions</a>.</p>
|
||
<p>Third, the standard library defines <a href="prelude/index.html" title="mod std::prelude">The Rust Prelude</a>, a small collection
|
||
of items - mostly traits - that are imported into every module of every
|
||
crate. The traits in the prelude are pervasive, making the prelude
|
||
documentation a good entry point to learning about the library.</p>
|
||
<p>And finally, the standard library exports a number of standard macros, and
|
||
<a href="#macros">lists them on this page</a> (technically, not all of the standard
|
||
macros are defined by the standard library - some are defined by the
|
||
compiler - but they are documented here the same). Like the prelude, the
|
||
standard macros are imported by default into all crates.</p>

|
||
<p>The rest of this crate documentation is dedicated to pointing out notable
|
||
features of The Rust Standard Library.</p>
|
||
<h3 id="containers-and-collections"><a class="doc-anchor" href="#containers-and-collections">§</a>Containers and collections</h3>
|
||
<p>The <a href="option/index.html" title="mod std::option"><code>option</code></a> and <a href="result/index.html" title="mod std::result"><code>result</code></a> modules define optional and error-handling
|
||
types, <a href="option/enum.Option.html" title="enum std::option::Option"><code>Option<T></code></a> and <a href="result/enum.Result.html" title="enum std::result::Result"><code>Result<T, E></code></a>. The <a href="iter/index.html" title="mod std::iter"><code>iter</code></a> module defines
|
||
Rust’s iterator trait, <a href="iter/trait.Iterator.html" title="trait std::iter::Iterator"><code>Iterator</code></a>, which works with the <a href="../book/ch03-05-control-flow.html#looping-through-a-collection-with-for"><code>for</code></a> loop to
|
||
access collections.</p>
|
||
<p>The standard library exposes three common ways to deal with contiguous
|
||
regions of memory:</p>
|
||
<ul>
|
||
<li><a href="vec/struct.Vec.html" title="struct std::vec::Vec"><code>Vec<T></code></a> - A heap-allocated <em>vector</em> that is resizable at runtime.</li>
|
||
<li><a href="primitive.array.html" title="primitive array"><code>[T; N]</code></a> - An inline <em>array</em> with a fixed size at compile time.</li>
|
||
<li><a href="primitive.slice.html" title="primitive slice"><code>[T]</code></a> - A dynamically sized <em>slice</em> into any other kind of contiguous
|
||
storage, whether heap-allocated or not.</li>
|
||
</ul>
|
||
<p>Slices can only be handled through some kind of <em>pointer</em>, and as such come
|
||
in many flavors such as:</p>
|
||
<ul>
|
||
<li><code>&[T]</code> - <em>shared slice</em></li>
|
||
<li><code>&mut [T]</code> - <em>mutable slice</em></li>
|
||
<li><a href="boxed/index.html" title="mod std::boxed"><code>Box<[T]></code></a> - <em>owned slice</em></li>
|
||
</ul>
|
||
<p><a href="primitive.str.html" title="primitive str"><code>str</code></a>, a UTF-8 string slice, is a primitive type, and the standard library
|
||
defines many methods for it. Rust <a href="primitive.str.html" title="primitive str"><code>str</code></a>s are typically accessed as
|
||
immutable references: <code>&str</code>. Use the owned <a href="string/struct.String.html" title="struct std::string::String"><code>String</code></a> for building and
|
||
mutating strings.</p>
|
||
<p>For converting to strings use the <a href="macro.format.html" title="macro std::format"><code>format!</code></a> macro, and for converting from
|
||
strings use the <a href="str/trait.FromStr.html" title="trait std::str::FromStr"><code>FromStr</code></a> trait.</p>
|
||
<p>Data may be shared by placing it in a reference-counted box or the <a href="rc/struct.Rc.html" title="struct std::rc::Rc"><code>Rc</code></a>
|
||
type, and if further contained in a <a href="cell/struct.Cell.html" title="struct std::cell::Cell"><code>Cell</code></a> or <a href="cell/struct.RefCell.html" title="struct std::cell::RefCell"><code>RefCell</code></a>, may be mutated
|
||
as well as shared. Likewise, in a concurrent setting it is common to pair an
|
||
atomically-reference-counted box, <a href="sync/struct.Arc.html" title="struct std::sync::Arc"><code>Arc</code></a>, with a <a href="sync/struct.Mutex.html" title="struct std::sync::Mutex"><code>Mutex</code></a> to get the same
|
||
effect.</p>
|
||
<p>The <a href="collections/index.html" title="mod std::collections"><code>collections</code></a> module defines maps, sets, linked lists and other
|
||
typical collection types, including the common <a href="collections/struct.HashMap.html" title="struct std::collections::HashMap"><code>HashMap<K, V></code></a>.</p>
|
||
<h3 id="platform-abstractions-and-io"><a class="doc-anchor" href="#platform-abstractions-and-io">§</a>Platform abstractions and I/O</h3>
|
||
<p>Besides basic data types, the standard library is largely concerned with
|
||
abstracting over differences in common platforms, most notably Windows and
|
||
Unix derivatives.</p>
|
||
<p>Common types of I/O, including <a href="fs/struct.File.html" title="struct std::fs::File">files</a>, <a href="net/struct.TcpStream.html" title="struct std::net::TcpStream">TCP</a>, and <a href="net/struct.UdpSocket.html" title="struct std::net::UdpSocket">UDP</a>, are defined in
|
||
the <a href="io/index.html" title="mod std::io"><code>io</code></a>, <a href="fs/index.html" title="mod std::fs"><code>fs</code></a>, and <a href="net/index.html" title="mod std::net"><code>net</code></a> modules.</p>
|
||
<p>The <a href="thread/index.html" title="mod std::thread"><code>thread</code></a> module contains Rust’s threading abstractions. <a href="sync/index.html" title="mod std::sync"><code>sync</code></a>
|
||
contains further primitive shared memory types, including <a href="sync/atomic/index.html" title="mod std::sync::atomic"><code>atomic</code></a>, <a href="sync/mpmc/index.html" title="mod std::sync::mpmc"><code>mpmc</code></a> and
|
||
<a href="sync/mpsc/index.html" title="mod std::sync::mpsc"><code>mpsc</code></a>, which contains the channel types for message passing.</p>
|
||
<h2 id="use-before-and-after-main"><a class="doc-anchor" href="#use-before-and-after-main">§</a>Use before and after <code>main()</code></h2>
|
||
<p>Many parts of the standard library are expected to work before and after <code>main()</code>;
|
||
but this is not guaranteed or ensured by tests. It is recommended that you write your own tests
|
||
and run them on each platform you wish to support.
|
||
This means that use of <code>std</code> before/after main, especially of features that interact with the
|
||
OS or global state, is exempted from stability and portability guarantees and instead only
|
||
provided on a best-effort basis. Nevertheless bug reports are appreciated.</p>
|
||
<p>On the other hand <code>core</code> and <code>alloc</code> are most likely to work in such environments with
|
||
the caveat that any hookable behavior such as panics, oom handling or allocators will also
|
||
depend on the compatibility of the hooks.</p>
|
||
<p>Some features may also behave differently outside main, e.g. stdio could become unbuffered,
|
||
some panics might turn into aborts, backtraces might not get symbolicated or similar.</p>
|
||
<p>Non-exhaustive list of known limitations:</p>
|
||
<ul>
|
||
<li>after-main use of thread-locals, which also affects additional features:
|
||
<ul>
|
||
<li><a href="thread/fn.current.html" title="fn std::thread::current"><code>thread::current()</code></a></li>
|
||
</ul>
|
||
</li>
|
||
<li>under UNIX, before main, file descriptors 0, 1, and 2 may be unchanged
|
||
(they are guaranteed to be open during main,
|
||
and are opened to /dev/null O_RDWR if they weren’t open on program start)</li>
