# Mio Metal IO
Mio is a lightweight I/O library for Rust with a focus on adding as little
overhead as possible over the OS abstractions.

**API documentation**
* [master](https://tokio-rs.github.io/mio/doc/mio/)
* [v0.6](https://docs.rs/mio/^0.6)
This is a low level library, if you are looking for something easier to get
started with, see [Tokio](https://tokio.rs).
## Usage
To use `mio`, first add this to your `Cargo.toml`:
```toml
[dependencies]
mio = "0.6"
```
Then, add this to your crate root:
```rust
extern crate mio;
```
## Features
* Non-blocking TCP, UDP
* I/O event queue backed by epoll, kqueue, and IOCP
* Zero allocations at runtime
* Platform specific extensions
## Non-goals
The following are specifically omitted from Mio and are left to the user
or higher-level libraries.
* File operations
* Thread pools / multi-threaded event loop
* Timers
## Platforms
Currently supported platforms:
* Android
* Bitrig
* DragonFly BSD
* FreeBSD
* Linux
* NetBSD
* OpenBSD
* Solaris
* Windows
* iOS
* macOS
There are potentially others. If you find that Mio works on another
platform, submit a PR to update the list!
## Community
A group of Mio users hang out on [Gitter], this can be a good place to go for
questions.
[Gitter]: https://gitter.im/tokio-rs/mio
## Contributing
Interested in getting involved? We would love to help you! For simple
bug fixes, just submit a PR with the fix and we can discuss the fix
directly in the PR. If the fix is more complex, start with an issue.
If you want to propose an API change, create an issue to start a
discussion with the community. Also, feel free to talk with us in the
IRC channel.
Finally, be kind. We support the [Rust Code of Conduct](https://www.rust-lang.org/policies/code-of-conduct).

other entities that control, are controlled by, or are under common
control with that entity. For the purposes of this definition,
"control" means (i) the power, direct or indirect, to cause the
direction or management of such entity, whether by contract or
otherwise, or (ii) ownership of fifty percent (50%) or more of the
outstanding shares, or (iii) beneficial ownership of such entity.
"You" (or "Your") shall mean an individual or Legal Entity
exercising permissions granted by this License.
"Source" form shall mean the preferred form for making modifications,
including but not limited to software source code, documentation
source, and configuration files.
"Object" form shall mean any form resulting from mechanical
transformation or translation of a Source form, including but
not limited to compiled object code, generated documentation,
and conversions to other media types.
"Work" shall mean the work of authorship, whether in Source or
Object form, made available under the License, as indicated by a
copyright notice that is included in or attached to the work
(an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the
editorial revisions, annotations, elaborations, or other modifications
represent, as a whole, an original work of authorship. For the purposes
of this License, Derivative Works shall not include works that remain
separable from, or merely link (or bind by name) to the interfaces of,
the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of
the copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent
to the Licensor or its representatives, including but not limited to
communication on electronic mailing lists, source code control systems,
and issue tracking systems that are managed by, or on behalf of, the
Licensor for the purpose of discussing and improving the Work, but
excluding communication that is conspicuously marked or otherwise
designated in writing by the copyright owner as "Not a Contribution."
"Contributor" shall mean Licensor and any individual or Legal Entity
on behalf of whom a Contribution has been received by Licensor and
subsequently incorporated within the Work.
2. Grant of Copyright License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.
END OF TERMS AND CONDITIONS

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and

with others.
The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.

aforementioned platforms. The details of their implementation are further
discussed in <a href="struct.Poll.html"><code>Poll</code></a>.</p>
<h1 id="usage" class="section-header"><a href="#usage">Usage</a></h1>
<p>Using Mio starts by creating a <a href="struct.Poll.html"><code>Poll</code></a>, which reads events from the OS and
puts them into <a href="struct.Events.html"><code>Events</code></a>. You can handle IO events from the OS with it.</p>
<p>For more detail, see <a href="struct.Poll.html"><code>Poll</code></a>.</p>

<p><code>Poll</code> allows a program to monitor a large number of <a href="crate::event::Source"><code>event::Source</code></a>s,
waiting until one or more become &quot;ready&quot; for some class of operations; e.g.
reading and writing. An event source is considered ready if it is possible
to immediately perform a corresponding operation; e.g. <a href="tcp/struct.TcpStream.html#method.read"><code>read</code></a> or
<a href="tcp/struct.TcpStream.html#method.write"><code>write</code></a>.</p>
<p>To use <code>Poll</code>, an <code>event::Source</code> must first be registered with the <code>Poll</code>
instance using the <a href="#method.register"><code>register</code></a> method on its associated <code>Register</code>,
supplying readiness interest. The readiness interest tells <code>Poll</code> which
specific operations on the handle to monitor for readiness. A <code>Token</code> is
also passed to the <a href="#method.register"><code>register</code></a> function. When <code>Poll</code> returns a readiness
event, it will include this token. This associates the event with the
event source that generated the event.</p>

<h1 id="portability" class="section-header"><a href="#portability">Portability</a></h1>
<p>Using <code>Poll</code> provides a portable interface across supported platforms as
long as the caller takes the following into consideration:</p>
<h3 id="spurious-events" class="section-header"><a href="#spurious-events">Spurious events</a></h3>
<p><a href="struct.Poll.html#method.poll"><code>Poll::poll</code></a> may return readiness events even if the associated
event source is not actually ready. Given the same code, this may
happen more on some platforms than others. It is important to never assume
that, just because a readiness event was received, that the associated
operation will succeed as well.</p>
<p>If operation fails with <a href="std::io::ErrorKind::WouldBlock"><code>WouldBlock</code></a>, then the caller should not treat
this as an error, but instead should wait until another readiness event is
received.</p>
<h3 id="draining-readiness" class="section-header"><a href="#draining-readiness">Draining readiness</a></h3>
<p>Once a readiness event is received, the corresponding operation must be
performed repeatedly until it returns <a href="std::io::ErrorKind::WouldBlock"><code>WouldBlock</code></a>. Unless this is done,
there is no guarantee that another readiness event will be delivered, even
if further data is received for the event source.</p>
<h3 id="readiness-operations" class="section-header"><a href="#readiness-operations">Readiness operations</a></h3>
<p>The only readiness operations that are guaranteed to be present on all
supported platforms are <a href="crate::event::Event::is_readable"><code>readable</code></a> and <a href="crate::event::Event::is_writable"><code>writable</code></a>. All other readiness
operations may have false negatives and as such should be considered
<strong>hints</strong>. This means that if a socket is registered with <a href="crate::event::Event::is_readable"><code>readable</code></a>,
<a href="crate::event::Event::is_error"><code>error</code></a>, and <a href="crate::event::Event::is_hup"><code>hup</code></a> interest, and either an error or hup is received, a
readiness event will be generated for the socket, but it <strong>may</strong> only
include <code>readable</code> readiness. Also note that, given the potential for
spurious events, receiving a readiness event with <code>hup</code> or <code>error</code> doesn't
actually mean that a <code>read</code> on the socket will return a result matching the
readiness event.</p>
<p>In other words, portable programs that explicitly check for <a href="crate::event::Event::is_hup"><code>hup</code></a> or
<a href="crate::event::Event::is_error"><code>error</code></a> readiness should be doing so as an <strong>optimization</strong> and always be
able to handle an error or HUP situation when performing the actual read
operation.</p>
<h3 id="registering-handles" class="section-header"><a href="#registering-handles">Registering handles</a></h3>
<p>Unless otherwise noted, it should be assumed that types implementing
<a href="crate::event::Source"><code>event::Source</code></a> will never become ready unless they are registered with
<code>Poll</code>.</p>

<p>On all supported platforms, socket operations are handled by using the
system selector. Platform specific extensions (e.g. <a href="unix/struct.SourceFd.html"><code>SourceFd</code></a>) allow
accessing other features provided by individual system selectors. For
example, Linux's <a href="http://man7.org/linux/man-pages/man2/signalfd.2.html"><code>signalfd</code></a> feature can be used by registering the FD with
<code>Poll</code> via <a href="unix/struct.SourceFd.html"><code>SourceFd</code></a>.</p>
<p>On all platforms except windows, a call to <a href="struct.Poll.html#method.poll"><code>Poll::poll</code></a> is mostly just a
direct call to the system selector. However, <a href="https://msdn.microsoft.com/en-us/library/windows/desktop/aa365198(v=vs.85).aspx">IOCP</a> uses a completion model
instead of a readiness model. In this case, <code>Poll</code> must adapt the completion
model Mio's API. While non-trivial, the bridge layer is still quite
efficient. The most expensive part being calls to <code>read</code> and <code>write</code> require
data to be copied into an intermediate buffer before it is passed to the
kernel.</p>
<p>Notifications generated by <a href="struct.SetReadiness.html"><code>SetReadiness</code></a> are handled by an internal
readiness queue. A single call to <a href="struct.Poll.html#method.poll"><code>Poll::poll</code></a> will collect events from
both from the system selector and the internal readiness queue.</p>

<p>Blocks the current thread and waits for readiness events for any of the
<a href="crate::event::Source"><code>event::Source</code></a>s that have been registered with this <code>Poll</code> instance.
The function will block until either at least one readiness event has
been received or <code>timeout</code> has elapsed. A <code>timeout</code> of <code>None</code> means that
<code>poll</code> will block until a readiness event has been received.</p>
<p>The supplied <code>events</code> will be cleared and newly received readiness events
will be pushed onto the end. At most <code>events.capacity()</code> events will be
returned. If there are further pending readiness events, they will be
returned on the next call to <code>poll</code>.</p>
<p>A single call to <code>poll</code> may result in multiple readiness events being
returned for a single event source. For example, if a TCP socket becomes
both readable and writable, it may be possible for a single readiness
event to be returned with both <a href="struct.Interests.html#method.readable"><code>readable</code></a> and <a href="struct.Interests.html#method.writable"><code>writable</code></a> readiness
<strong>OR</strong> two separate events may be returned, one with <a href="struct.Interests.html#method.readable"><code>readable</code></a> set
and one with <a href="struct.Interests.html#method.writable"><code>writable</code></a> set.</p>
<p>Note that the <code>timeout</code> will be rounded up to the system clock
granularity (usually 1ms), and kernel scheduling delays mean that
the blocking interval may be overrun by a small amount.</p>
<p><code>poll</code> returns the number of readiness events that have been pushed into
<code>events</code> or <code>Err</code> when an error has been encountered with the system
selector. The value returned is deprecated and will be removed in 0.7.0.
Accessing the events by index is also deprecated. Events can be
inserted by other events triggering, thus making sequential access
problematic. Use the iterator API instead. See <a href="struct.Events.html#method.iter"><code>iter</code></a>.</p>
<p>See the <a href="#">struct</a> level documentation for a higher level discussion of
polling.</p>

<p><code>source: &amp;S: event::Source</code>: This is the source of events that the
<code>Poll</code> instance should monitor for readiness state changes.</p>
<p><code>token: Token</code>: The caller picks a token to associate with the socket.
When <a href="#method.poll"><code>poll</code></a> returns an event for the handle, this token is included.
This allows the caller to map the event to its handle. The token
associated with the <code>event::Source</code> can be changed at any time by
calling <a href="#method.reregister"><code>reregister</code></a>.</p>
<p><code>token</code> cannot be <code>Token(usize::MAX)</code> as it is reserved for internal
usage.</p>
<p>See documentation on <a href="struct.Token.html"><code>Token</code></a> for an example showing how to pick
<a href="struct.Token.html"><code>Token</code></a> values.</p>
<p><code>interest: Interests</code>: Specifies which operations <code>Poll</code> should monitor
for readiness. <code>Poll</code> will only return readiness events for operations
specified by this argument.</p>
<p>If a socket is registered with readable interest and the socket becomes
writable, no event will be returned from <a href="#method.poll"><code>poll</code></a>.</p>
<p>The readiness interest for an <code>event::Source</code> can be changed at any time
by calling <a href="#method.reregister"><code>reregister</code></a>.</p>
<h1 id="notes" class="section-header"><a href="#notes">Notes</a></h1>
<p>Unless otherwise specified, the caller should assume that once an event
source is registered with a <code>Poll</code> instance, it is bound to that <code>Poll</code>
instance for the lifetime of the event source. This remains true even
if the event source is deregistered from the poll instance using
<a href="#method.deregister"><code>deregister</code></a>.</p>
<p>This function is <strong>thread safe</strong>. It can be called concurrently from
multiple threads.</p>

<p><code>SourceFd</code> enables registering any type with an FD with <a href="crate::Poll"><code>Poll</code></a>.</p>
<p>While only implementations for TCP and UDP are provided, Mio supports
registering any FD that can be registered with the underlying OS selector.
<code>SourceFd</code> provides the necessary bridge.</p>
<p>Note that <code>SourceFd</code> takes a <code>&amp;RawFd</code>. This is because <code>SourceFd</code> <strong>does
not</strong> take ownership of the FD. Specifically, it will not manage any
lifecycle related operations, such as closing the FD on drop. It is expected
that the <code>SourceFd</code> is constructed right before a call to
<a href="crate::Registry::register"><code>Registry::register</code></a>. See the examples for more detail.</p>
