std::net::SocketAddrV4 - Rust
Description: API documentation for the Rust `SocketAddrV4` struct in crate `std`.
Keywords: rust, rustlang, rust-lang, SocketAddrV4

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

    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.

# 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

## Methods

### `impl SocketAddrV4`
[src]

#### `pub fn new(ip: Ipv4Addr, port: u16) -> SocketAddrV4`
[src]

Creates a new socket address from an IPv4 address and a port number.

# Examples

    use std::net::{SocketAddrV4, Ipv4Addr};

    let socket = SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 8080);Run

#### `pub fn ip(&self) -> &Ipv4Addr`
[src]

Returns the IP address associated with this socket address.

# Examples

    use std::net::{SocketAddrV4, Ipv4Addr};

    let socket = SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 8080);
    assert_eq!(socket.ip(), &Ipv4Addr::new(127, 0, 0, 1));Run

#### `pub fn set_ip(&mut self, new_ip: Ipv4Addr)`
1.9.0
[src]

Changes the IP address associated with this socket address.

# Examples

    use std::net::{SocketAddrV4, Ipv4Addr};

    let mut socket = SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 8080);
    socket.set_ip(Ipv4Addr::new(192, 168, 0, 1));
    assert_eq!(socket.ip(), &Ipv4Addr::new(192, 168, 0, 1));Run

#### `pub fn port(&self) -> u16`
[src]

Returns the port number associated with this socket address.

# Examples

    use std::net::{SocketAddrV4, Ipv4Addr};

    let socket = SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 8080);
    assert_eq!(socket.port(), 8080);Run

#### `pub fn set_port(&mut self, new_port: u16)`
1.9.0
[src]

Changes the port number associated with this socket address.

# Examples

    use std::net::{SocketAddrV4, Ipv4Addr};

    let mut socket = SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 8080);
    socket.set_port(4242);
    assert_eq!(socket.port(), 4242);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`)
