|
||||
<p>This module is the asynchronous version of <code>std::io</code>. Primarily, it
|
||||
defines two traits, <a href="../../tokio/io/trait.AsyncRead.html"><code>AsyncRead</code></a> and <a href="../../tokio/io/trait.AsyncWrite.html"><code>AsyncWrite</code></a>, which are asynchronous
|
||||
versions of the <a href="https://doc.rust-lang.org/nightly/std/io/trait.Read.html"><code>Read</code></a> and <a href="https://doc.rust-lang.org/nightly/std/io/trait.Write.html"><code>Write</code></a> traits in the standard library.</p>
|
||||
<h1 id="asyncread-and-asyncwrite" class="section-header"><a href="#asyncread-and-asyncwrite">AsyncRead and AsyncWrite</a></h1>
|
||||
<p>Like the standard library's <a href="https://doc.rust-lang.org/nightly/std/io/trait.Read.html"><code>Read</code></a> and <a href="https://doc.rust-lang.org/nightly/std/io/trait.Write.html"><code>Write</code></a> traits, <a href="../../tokio/io/trait.AsyncRead.html"><code>AsyncRead</code></a> and
|
||||
<a href="../../tokio/io/trait.AsyncWrite.html"><code>AsyncWrite</code></a> provide the most general interface for reading and writing
|
||||
input and output. Unlike the standard library's traits, however, they are
|
||||
<em>asynchronous</em> — meaning that reading from or writing to a <code>tokio::io</code>
|
||||
type will <em>yield</em> to the Tokio scheduler when IO is not ready, rather than
|
||||
blocking. This allows other tasks to run while waiting on IO.</p>
|
||||
<p>Another difference is that <code>AsyncRead</code> and <code>AsyncWrite</code> only contain
|
||||
core methods needed to provide asynchronous reading and writing
|
||||
functionality. Instead, utility methods are defined in the <a href="trait@AsyncReadExt"><code>AsyncReadExt</code></a>
|
||||
and <a href="trait@AsyncWriteExt"><code>AsyncWriteExt</code></a> extension traits. These traits are automatically
|
||||
implemented for all values that implement <code>AsyncRead</code> and <code>AsyncWrite</code>
|
||||
respectively.</p>
|
||||
<p>End users will rarely interact directly with <code>AsyncRead</code> and
|
||||
<code>AsyncWrite</code>. Instead, they will use the async functions defined in the
|
||||
extension traits. Library authors are expected to implement <code>AsyncRead</code>
|
||||
and <code>AsyncWrite</code> in order to provide types that behave like byte streams.</p>
|
||||
<p>Even with these differences, Tokio's <code>AsyncRead</code> and <code>AsyncWrite</code> traits
|
||||
can be used in almost exactly the same manner as the standard library's
|
||||
<code>Read</code> and <code>Write</code>. Most types in the standard library that implement <code>Read</code>
|
||||
and <code>Write</code> have asynchronous equivalents in <code>tokio</code> that implement
|
||||
<code>AsyncRead</code> and <code>AsyncWrite</code>, such as <a href="crate::fs::File"><code>File</code></a> and <a href="../../tokio/net/struct.TcpStream.html"><code>TcpStream</code></a>.</p>
|
||||
<p>For example, the standard library documentation introduces <code>Read</code> by
|
||||
<a href="https://doc.rust-lang.org/nightly/std/io/index.html#read-and-write">demonstrating</a> reading some bytes from a <a href="https://doc.rust-lang.org/nightly/std/fs/struct.File.html"><code>std::fs::File</code></a>. We
|
||||
can do the same with <a href="crate::fs::File"><code>tokio::fs::File</code></a>:</p>

<h2 id="buffered-readers-and-writers" class="section-header"><a href="#buffered-readers-and-writers">Buffered Readers and Writers</a></h2>
|
||||
<p>Byte-based interfaces are unwieldy and can be inefficient, as we'd need to be
|
||||
making near-constant calls to the operating system. To help with this,
|
||||
<code>std::io</code> comes with <a href="https://doc.rust-lang.org/nightly/std/io/index.html#bufreader-and-bufwriter">support for <em>buffered</em> readers and writers</a>,
|
||||
and therefore, <code>tokio::io</code> does as well.</p>
|
||||
<p>Tokio provides an async version of the <a href="https://doc.rust-lang.org/nightly/std/io/trait.BufRead.html"><code>std::io::BufRead</code></a> trait,
|
||||
<a href="../../tokio/io/trait.AsyncBufRead.html"><code>AsyncBufRead</code></a>; and async <a href="crate::io::BufReader"><code>BufReader</code></a> and <a href="crate::io::BufWriter"><code>BufWriter</code></a> structs, which
|
||||
wrap readers and writers. These wrappers use a buffer, reducing the number
|
||||
of calls and providing nicer methods for accessing exactly what you want.</p>
|
||||
<p>For example, <a href="crate::io::BufReader"><code>BufReader</code></a> works with the <a href="../../tokio/io/trait.AsyncBufRead.html"><code>AsyncBufRead</code></a> trait to add
|
||||
extra methods to any async reader:</p>

<p>Because they are traits, we can implement <a href="../../tokio/io/trait.AsyncRead.html"><code>AsyncRead</code></a> and <a href="../../tokio/io/trait.AsyncWrite.html"><code>AsyncWrite</code></a> for
|
||||
our own types, as well. Note that these traits must only be implemented for
|
||||
non-blocking I/O types that integrate with the futures type system. In
|
||||
other words, these types must never block the thread, and instead the
|
||||
current task is notified when the I/O resource is ready.</p>

type that is encoded as bytes and/or decoded from bytes. Tokio
|

provides some utility traits in the <a href="https://docs.rs/tokio-util/0.6/tokio_util/codec/index.html">tokio-util</a> crate that
|

abstract the asynchronous buffering that is required and allows
|
||||
you to write <a href="https://docs.rs/tokio-util/0.6/tokio_util/codec/trait.Encoder.html"><code>Encoder</code></a> and <a href="https://docs.rs/tokio-util/0.6/tokio_util/codec/trait.Decoder.html"><code>Decoder</code></a> functions working with a
|
||||
buffer of bytes, and then use that <a href="https://docs.rs/tokio-util/0.6/tokio_util/codec/index.html">"codec"</a> to transform anything
|

that implements <a href="../../tokio/io/trait.AsyncRead.html"><code>AsyncRead</code></a> and <a href="../../tokio/io/trait.AsyncWrite.html"><code>AsyncWrite</code></a> into a <code>Sink</code>/<code>Stream</code> of

<h1 id="standard-input-and-output" class="section-header"><a href="#standard-input-and-output">Standard input and output</a></h1>
|
||||
<p>Tokio provides asynchronous APIs to standard <a href="fn@stdin">input</a>, <a href="fn@stdout">output</a>, and <a href="fn@stderr">error</a>.
|
||||
These APIs are very similar to the ones provided by <code>std</code>, but they also
|
||||
implement <a href="../../tokio/io/trait.AsyncRead.html"><code>AsyncRead</code></a> and <a href="../../tokio/io/trait.AsyncWrite.html"><code>AsyncWrite</code></a>.</p>
|
||||
<p>Note that the standard input / output APIs <strong>must</strong> be used from the
|
||||
context of the Tokio runtime, as they require Tokio-specific features to
|
||||
function. Calling these functions outside of a Tokio runtime will panic.</p>

|
||||
<p>This type is a sort of "double cursor". It tracks three regions in the
|
||||
buffer: a region at the beginning of the buffer that has been logically
|
||||
filled with data, a region that has been initialized at some point but not
|
||||
yet logically filled, and a region at the end that may be uninitialized.
|
||||
The filled region is guaranteed to be a subset of the initialized region.</p>
|
||||
<p>In summary, the contents of the buffer can be visualized as:</p>
|
||||
<pre><code class="language-not_rust">[ capacity ]
|
||||
[ filled | unfilled ]
|
||||
[ initialized | uninitialized ]
|
||||
</code></pre>
|
||||
<p>It is undefined behavior to de-initialize any bytes from the uninitialized
|
||||
region, since it is merely unknown whether this region is uninitialized or
|
||||
not, and if part of it turns out to be initialized, it must stay initialized.</p>

|
||||
reactor, allowing for readiness to be polled. The file descriptor must be of
|
||||
a type that can be used with the OS polling facilities (ie, <code>poll</code>, <code>epoll</code>,
|
||||
<code>kqueue</code>, etc), such as a network socket or pipe.</p>
|
||||
<p>Creating an AsyncFd registers the file descriptor with the current tokio
|
||||
Reactor, allowing you to directly await the file descriptor being readable
|
||||
or writable. Once registered, the file descriptor remains registered until
|
||||
the AsyncFd is dropped.</p>
|
||||
<p>The AsyncFd takes ownership of an arbitrary object to represent the IO
|
||||
object. It is intended that this object will handle closing the file
|
||||
descriptor when it is dropped, avoiding resource leaks and ensuring that the
|
||||
AsyncFd can clean up the registration before closing the file descriptor.
|
||||
The <a href="../../../tokio/io/unix/struct.AsyncFd.html#method.into_inner" title="AsyncFd::into_inner"><code>AsyncFd::into_inner</code></a> function can be used to extract the inner object
|
||||
to retake control from the tokio IO reactor.</p>
|
||||
<p>The inner object is required to implement <a href="https://doc.rust-lang.org/nightly/std/sys/unix/ext/io/trait.AsRawFd.html" title="AsRawFd"><code>AsRawFd</code></a>. This file descriptor
|
||||
must not change while <a href="../../../tokio/io/unix/struct.AsyncFd.html" title="AsyncFd"><code>AsyncFd</code></a> owns the inner object. Changing the file
|
||||
descriptor results in unspecified behavior in the IO driver, which may
|
||||
include breaking notifications for other sockets/etc.</p>
|
||||
<p>Polling for readiness is done by calling the async functions <a href="../../../tokio/io/unix/struct.AsyncFd.html#method.readable"><code>readable</code></a>
|
||||
and <a href="../../../tokio/io/unix/struct.AsyncFd.html#method.writable"><code>writable</code></a>. These functions complete when the associated readiness
|
||||
condition is observed. Any number of tasks can query the same <code>AsyncFd</code> in
|
||||
parallel, on the same or different conditions.</p>
|
||||
<p>On some platforms, the readiness detecting mechanism relies on
|
||||
edge-triggered notifications. This means that the OS will only notify Tokio
|
||||
when the file descriptor transitions from not-ready to ready. Tokio
|
||||
internally tracks when it has received a ready notification, and when
|
||||
readiness checking functions like <a href="../../../tokio/io/unix/struct.AsyncFd.html#method.readable"><code>readable</code></a> and <a href="../../../tokio/io/unix/struct.AsyncFd.html#method.writable"><code>writable</code></a> are called,
|
||||
if the readiness flag is set, these async functions will complete
|
||||
immediately.</p>
|
||||
<p>This however does mean that it is critical to ensure that this ready flag is
|
||||
cleared when (and only when) the file descriptor ceases to be ready. The
|
||||
<a href="../../../tokio/io/unix/struct.AsyncFdReadyGuard.html"><code>AsyncFdReadyGuard</code></a> returned from readiness checking functions serves this
|
||||
function; after calling a readiness-checking async function, you must use
|
||||
this <a href="../../../tokio/io/unix/struct.AsyncFdReadyGuard.html"><code>AsyncFdReadyGuard</code></a> to signal to tokio whether the file descriptor is no
|
||||
longer in a ready state.</p>
|
||||
<h2 id="use-with-to-a-poll-based-api" class="section-header"><a href="#use-with-to-a-poll-based-api">Use with to a poll-based API</a></h2>
|
||||
<p>In some cases it may be desirable to use <code>AsyncFd</code> from APIs similar to
|
||||
<a href="../../../tokio/net/struct.TcpStream.html"><code>TcpStream::poll_read_ready</code></a>. The <a href="../../../tokio/io/unix/struct.AsyncFd.html#method.poll_read_ready" title="AsyncFd::poll_read_ready"><code>AsyncFd::poll_read_ready</code></a> and
|
||||
<a href="../../../tokio/io/unix/struct.AsyncFd.html#method.poll_write_ready" title="AsyncFd::poll_write_ready"><code>AsyncFd::poll_write_ready</code></a> functions are provided for this purpose.
|
||||
Because these functions don't create a future to hold their state, they have
|
||||
the limitation that only one task can wait on each direction (read or write)
|
||||
at a time.</p>
|
||||
<h1 id="examples" class="section-header"><a href="#examples">Examples</a></h1>
|
||||
<p>This example shows how to turn <a href="https://doc.rust-lang.org/nightly/std/net/tcp/struct.TcpStream.html" title="std::net::TcpStream"><code>std::net::TcpStream</code></a> asynchronous using
|
||||
<code>AsyncFd</code>. It implements <code>read</code> as an async fn, and <code>AsyncWrite</code> as a trait
|
||||
to show how to implement both approaches.</p>

<p>If <code>f</code> returns a <a href="https://doc.rust-lang.org/nightly/std/io/error/enum.ErrorKind.html#variant.WouldBlock"><code>WouldBlock</code></a> error, the readiness state associated

with this file descriptor is cleared, and the method returns

<code>Err(TryIoError::WouldBlock)</code>. You will typically need to poll the

<code>AsyncFd</code> again when this happens.</p>
|

<p>This method helps ensure that the readiness state of the underlying file
|

descriptor remains in sync with the tokio-side readiness state, by

clearing the tokio-side state only when a <a href="https://doc.rust-lang.org/nightly/std/io/error/enum.ErrorKind.html#variant.WouldBlock"><code>WouldBlock</code></a> condition

occurs. It is the responsibility of the caller to ensure that <code>f</code>
|

returns <a href="https://doc.rust-lang.org/nightly/std/io/error/enum.ErrorKind.html#variant.WouldBlock"><code>WouldBlock</code></a> only if the file descriptor that originated this
|
||||
<code>AsyncFdReadyGuard</code> no longer expresses the readiness state that was queried to

create this <code>AsyncFdReadyGuard</code>.</p>
