Enum SocketAddr

1.77.0 · Source

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

Expand description

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.

The size of a SocketAddr instance may vary depending on the target operating system.

§Examples

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);

Variants§

§1.77.0

V4(SocketAddrV4)

An IPv4 socket address.

§1.77.0

V6(SocketAddrV6)

An IPv6 socket address.

impl SocketAddr

Source

pub fn parse_ascii(b: &[u8]) -> Result<Self, AddrParseError>

🔬This is a nightly-only experimental API. (addr_parse_ascii #101035)

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));
