# 1.0.0[−][src]Struct std::net::SocketAddrV4

    pub struct SocketAddrV4 { /* fields omitted */ }

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.

# 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);Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
