Expand description

Platform-specific extensions to SocketAddr.

Required Methods

🔬This is a nightly-only experimental API. (unix_socket_abstract #85410)

Creates a Unix socket address in the abstract namespace.

The abstract namespace is a Linux-specific extension that allows Unix sockets to be bound without creating an entry in the filesystem. Abstract sockets are unaffected by filesystem layout or permissions, and no cleanup is necessary when the socket is closed.

An abstract socket address name may contain any bytes, including zero.

Errors

Returns an error if the name is longer than SUN_LEN - 1.

Examples
#![feature(unix_socket_abstract)]
use std::os::unix::net::{UnixListener, SocketAddr};
use std::os::linux::net::SocketAddrExt;

fn main() -> std::io::Result<()> {
    let addr = SocketAddr::from_abstract_name(b"hidden")?;
    let listener = match UnixListener::bind_addr(&addr) {
        Ok(sock) => sock,
        Err(err) => {
            println!("Couldn't bind: {err:?}");
            return Err(err);
        }
    };
    Ok(())
}
Run
🔬This is a nightly-only experimental API. (unix_socket_abstract #85410)

Returns the contents of this address if it is in the abstract namespace.

Examples
#![feature(unix_socket_abstract)]
use std::os::unix::net::{UnixListener, SocketAddr};
use std::os::linux::net::SocketAddrExt;

fn main() -> std::io::Result<()> {
    let name = b"hidden";
    let name_addr = SocketAddr::from_abstract_name(name)?;
    let socket = UnixListener::bind_addr(&name_addr)?;
    let local_addr = socket.local_addr().expect("Couldn't get local address");
    assert_eq!(local_addr.as_abstract_name(), Some(&name[..]));
    Ok(())
}
