Struct std::os::unix::net::SocketAddr

pub struct SocketAddr { /* fields omitted */ }

This is supported on Unix only.

与 Unix 套接字关联的地址。

Examples

use std::os::unix::net::UnixListener;

let socket = match UnixListener::bind("/tmp/sock") {
    Ok(sock) => sock,
    Err(e) => {
        println!("Couldn't bind: {:?}", e);
        return
    }
};
let addr = socket.local_addr().expect("Couldn't get local address");

Implementations

impl SocketAddr

pub fn is_unnamed(&self) -> bool

如果地址未命名，则返回 true。

Examples

命名地址:

use std::os::unix::net::UnixListener;

fn main() -> std::io::Result<()> {
    let socket = UnixListener::bind("/tmp/sock")?;
    let addr = socket.local_addr().expect("Couldn't get local address");
    assert_eq!(addr.is_unnamed(), false);
    Ok(())
}

一个未命名的地址:

use std::os::unix::net::UnixDatagram;

fn main() -> std::io::Result<()> {
    let socket = UnixDatagram::unbound()?;
    let addr = socket.local_addr().expect("Couldn't get local address");
    assert_eq!(addr.is_unnamed(), true);
    Ok(())
}

pub fn as_pathname(&self) -> Option<&Path>

如果它是 pathname 地址，则返回该地址的内容。

Examples

带有路径名:

use std::os::unix::net::UnixListener;
use std::path::Path;

fn main() -> std::io::Result<()> {
    let socket = UnixListener::bind("/tmp/sock")?;
    let addr = socket.local_addr().expect("Couldn't get local address");
    assert_eq!(addr.as_pathname(), Some(Path::new("/tmp/sock")));
    Ok(())
}

没有路径名:

use std::os::unix::net::UnixDatagram;

fn main() -> std::io::Result<()> {
    let socket = UnixDatagram::unbound()?;
    let addr = socket.local_addr().expect("Couldn't get local address");
    assert_eq!(addr.as_pathname(), None);
    Ok(())
}

Trait Implementations
