Enum std::net::SocketAddr

1.0.0 · 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§

§

V4(SocketAddrV4)
