| <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/nightly/std/net/tcp/struct.TcpStream.html"><code>TcpStream</code></a> or <a href="https://doc.rust-lang.org/nightly/std/net/udp/struct.UdpSocket.html"><code>UdpSocket</code></a>, using the |
| <a href="https://doc.rust-lang.org/nightly/core/convert/trait.From.html" title="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 |
| there options without overwriting previously set options. We do this by |
| first getting the current settings, applying the desired changes and than |
| 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> |
