<p>The types provided in this module are non-blocking by default and are
|
||
designed to be portable across all supported Mio platforms. As long as the
|
||
<a href="../struct.Poll.html#portability">portability guidelines</a> are followed, the behavior should be identical no
|
||
matter the target platform.</p>
|
||
<h2 id="notes"><a class="doc-anchor" href="#notes">§</a>Notes</h2>
|
||
<p>When using a datagram based socket, i.e. <a href="struct.UdpSocket.html" title="struct mio::net::UdpSocket"><code>UdpSocket</code></a> or <a href="struct.UnixDatagram.html" title="struct mio::net::UnixDatagram"><code>UnixDatagram</code></a>,
|
||
its only possible to receive a packet once. This means that if you provide a
|
||
buffer that is too small you won’t be able to receive the data anymore. How
|
||
OSs deal with this situation is different for each OS:</p>
|
||
<ul>
|
||
<li>Unixes, such as Linux, FreeBSD and macOS, will simply fill the buffer and
|
||
return the amount of bytes written. This means that if the returned value
|
||
is equal to the size of the buffer it may have only written a part of the
|
||
packet (or the packet has the same size as the buffer).</li>
|
||
<li>Windows returns an <code>WSAEMSGSIZE</code> error.</li>
|
||
</ul>
|
||
<p>Mio does not change the value (either ok or error) returned by the OS, it’s
|
||
up to the user handle this. How to deal with these difference is still up
|
||
for debate, specifically in
|
||
<a href="https://github.com/rust-lang/rust/issues/55794">https://github.com/rust-lang/rust/issues/55794</a>. The best advice we can
|
||
give is to always call receive with a large enough buffer.</p>
