std::net::SocketAddr - Rust
Description: API documentation for the Rust `SocketAddr` enum in crate `std`.
Keywords: rust, rustlang, rust-lang, SocketAddr

# 1.0.0[−][src]Enum std::net::SocketAddr

    pub enum SocketAddr {
        V4(SocketAddrV4),
        V6(SocketAddrV6),
    }

An internet socket address, either IPv4 or IPv6.

Internet socket addresses consist of an IP address, a 16-bit port number, as well as possibly some version-dependent additional information. See `SocketAddrV4`'s and `SocketAddrV6`'s respective documentation for more details.

The size of a `SocketAddr` instance may vary depending on the target operating system.

# Examples

    use std::net::{IpAddr, Ipv4Addr, SocketAddr};

    let socket = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)), 8080);

    assert_eq!("127.0.0.1:8080".parse(), Ok(socket));
    assert_eq!(socket.port(), 8080);
    assert_eq!(socket.is_ipv4(), true);Run

## Variants

`V4(SocketAddrV4)`

An IPv4 socket address.

`V6(SocketAddrV6)`

An IPv6 socket address.

## 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`)
