Struct std::net::SocketAddrV4

1.0.0 · source ·

pub struct SocketAddrV4 { /* private fields */ }

Expand description

An IPv4 socket address.

IPv4 socket addresses consist of an IPv4 address and a 16-bit port number, as stated in IETF RFC 793.

See SocketAddr for a type encompassing both IPv4 and IPv6 socket addresses.

The size of a SocketAddrV4 struct may vary depending on the target operating system. Do not assume that this type has the same memory layout as the underlying system representation.

Examples

use std::net::{Ipv4Addr, SocketAddrV4};
let socket = SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 8080);
assert_eq!("127.0.0.1:8080".parse(), Ok(socket));
assert_eq!(socket.ip(), &Ipv4Addr::new(127, 0, 0, 1));
assert_eq!(socket.port(), 8080);
