Struct socket2::Socket

source ·

pub struct Socket { /* private fields */ }

Expand description

Owned wrapper around a system socket.

This type simply wraps an instance of a file descriptor (c_int) on Unix and an instance of SOCKET 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.

§Converting to and from other types

This type can be freely converted into the network primitives provided by the standard library, such as TcpStream or UdpSocket, using the From trait, see the example below.

§Notes

Some methods that set options on Socket 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 not atomic. This can lead to a data race when two threads are changing options in parallel.

§Examples

use std::net::{SocketAddr, TcpListener};
use socket2::{Socket, Domain, Type};

// create a TCP listener
let socket = Socket::new(Domain::IPV6, Type::STREAM, None)?;

let address: SocketAddr = "[::1]:12345".parse().unwrap();
let address = address.into();
socket.bind(&address)?;
socket.listen(128)?;

let listener: TcpListener = socket.into();
// ...
