SocketAddrV4 in core::net - Rust
Description: An IPv4 socket address.

# Struct core::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);
