SocketAddrV4 in std::net - Rust (original) (raw)
Struct 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.
§Portability
SocketAddrV4 is intended to be a portable representation of socket addresses and is likely not the 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 upon between builds.
§Textual representation
SocketAddrV4 provides a FromStr implementation. It accepts an IPv4 address in its textual representation, followed by a single :, followed by the port encoded as a decimal integer. Other formats are not accepted.
§Examples
use std:🥅:{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);🔬This is a nightly-only experimental API. (addr_parse_ascii #101035)
