SocketAddr in cap_std::net - Rust

pub enum SocketAddr {
    V4(SocketAddrV4),
    V6(SocketAddrV6),
}

An internet socket address, either IPv4 or IPv6.

Internet socket addresses consist of an IP address, a 16-bit port number, as well as possibly some version-dependent additional information. See SocketAddrV4’s and SocketAddrV6’s respective documentation for more details.

SocketAddr is intended to be a portable representation of socket addresses and is likely not the same as the internal socket address type used by the target operating system’s API. Like all repr(Rust) structs, however, its exact layout remains undefined and should not be relied upon between builds.

use std::net::{IpAddr, Ipv4Addr, SocketAddr};

let socket = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)), 8080);

assert_eq!("127.0.0.1:8080".parse(), Ok(socket));
assert_eq!(socket.port(), 8080);
assert_eq!(socket.is_ipv4(), true);

An IPv4 socket address.

An IPv6 socket address.

Parse a socket address from a slice of bytes.

#![feature(addr_parse_ascii)]

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr, SocketAddr};

let socket_v4 = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)), 8080);
let socket_v6 = SocketAddr::new(IpAddr::V6(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1)), 8080);

assert_eq!(SocketAddr::parse_ascii(b"127.0.0.1:8080"), Ok(socket_v4));
assert_eq!(SocketAddr::parse_ascii(b"[::1]:8080"), Ok(socket_v6));

Creates a new socket address from an IP address and a port number.

use std::net::{IpAddr, Ipv4Addr, SocketAddr};

let socket = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)), 8080);
assert_eq!(socket.ip(), IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)));
assert_eq!(socket.port(), 8080);

Returns the IP address associated with this socket address.

use std::net::{IpAddr, Ipv4Addr, SocketAddr};

let socket = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)), 8080);
assert_eq!(socket.ip(), IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)));

Changes the IP address associated with this socket address.

use std::net::{IpAddr, Ipv4Addr, SocketAddr};

let mut socket = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)), 8080);
socket.set_ip(IpAddr::V4(Ipv4Addr::new(10, 10, 0, 1)));
assert_eq!(socket.ip(), IpAddr::V4(Ipv4Addr::new(10, 10, 0, 1)));

Returns the port number associated with this socket address.

use std::net::{IpAddr, Ipv4Addr, SocketAddr};

let socket = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)), 8080);
assert_eq!(socket.port(), 8080);

Changes the port number associated with this socket address.

use std::net::{IpAddr, Ipv4Addr, SocketAddr};

let mut socket = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)), 8080);
socket.set_port(1025);
assert_eq!(socket.port(), 1025);

Returns true if the IP address in this SocketAddr is an IPv4 address, and false otherwise.

use std::net::{IpAddr, Ipv4Addr, SocketAddr};

let socket = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)), 8080);
assert_eq!(socket.is_ipv4(), true);
assert_eq!(socket.is_ipv6(), false);

Returns true if the IP address in this SocketAddr is an IPv6 address, and false otherwise.

use std::net::{IpAddr, Ipv6Addr, SocketAddr};

let socket = SocketAddr::new(IpAddr::V6(Ipv6Addr::new(0, 0, 0, 0, 0, 65535, 0, 1)), 8080);
assert_eq!(socket.is_ipv4(), false);
assert_eq!(socket.is_ipv6(), true);

The associated error which can be returned from parsing.

Parses a string

to return a value of this type.

Tests for self and other values to be equal, and is used by ==.

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

This method returns an ordering between

and

values if one exists.

Tests less than (for

and

) and is used by the

operator.

Tests less than or equal to (for

and

) and is used by the

operator.

Tests greater than (for

and

) and is used by the

operator.

Tests greater than or equal to (for

and

) and is used by the

operator.

Returned iterator over socket addresses which this type may correspond to.
