pub struct SocketAddrV4 {/* private fields */ }
Expand description

An IPv4 socket address.

IPv4 socket addresses consist of anIPv4 address and a 16-bit port number, asstated inIETF RFC 793.

SeeSocketAddr for a type encompassing both IPv4 and IPv6 socket addresses.

§Portability

SocketAddrV4 is intended to be a portable representation of socket addresses and is likely notthe same as the internal socket address type used by the target operating system’s API. Like allrepr(Rust) structs, however, its exact layout remains undefined and should not be relied uponbetween builds.

§Textual representation

SocketAddrV4 provides aFromStr implementation.It accepts an IPv4 address in itstextual representation, followed by asingle:, followed by the port encoded as a decimal integer. Otherformats are not accepted.

§Examples

usestd::net::{Ipv4Addr, SocketAddrV4};letsocket = 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);
