<p>This type simply wraps an instance of a file descriptor (<code>c_int</code>) on Unix
and an instance of <code>SOCKET</code> on Windows. This is the main type exported by
this crate and is intended to mirror the raw semantics of sockets on
platforms as closely as possible. Almost all methods correspond to
precisely one libc or OS API call which is essentially just a “Rustic
translation” of what’s below.</p>
<h3 id="converting-to-and-from-other-types"><a href="#converting-to-and-from-other-types">Converting to and from other types</a></h3>
<p>This type can be freely converted into the network primitives provided by
the standard library, such as <a href="https://doc.rust-lang.org/1.76.0/std/net/tcp/struct.TcpStream.html" title="struct std::net::tcp::TcpStream"><code>TcpStream</code></a> or <a href="https://doc.rust-lang.org/1.76.0/std/net/udp/struct.UdpSocket.html" title="struct std::net::udp::UdpSocket"><code>UdpSocket</code></a>, using the
<a href="https://doc.rust-lang.org/1.76.0/core/convert/trait.From.html" title="trait core::convert::From"><code>From</code></a> trait, see the example below.</p>
<h2 id="notes"><a href="#notes">Notes</a></h2>
<p>Some methods that set options on <code>Socket</code> require two system calls to set
their options without overwriting previously set options. We do this by
first getting the current settings, applying the desired changes, and then
updating the settings. This means that the operation is <strong>not</strong> atomic. This
can lead to a data race when two threads are changing options in parallel.</p>
