pub fn set_read_timeout(&self, dur: Option<Duration>) -> Result<()>

🔬This is a nightly-only experimental API. (windows_unix_domain_sockets #150487)

Examples

#![feature(windows_unix_domain_sockets)]
use std::os::windows::net::UnixStream;
use std::time::Duration;

fn main() -> std::io::Result<()> {
    let socket = UnixStream::connect("/tmp/sock")?;
    socket.set_read_timeout(Some(Duration::new(1, 0))).expect("Couldn't set read timeout");
    Ok(())
}

An Err is returned if the zero Duration is passed to this method:

#![feature(windows_unix_domain_sockets)]
use std::io;
use std::os::windows::net::UnixStream;
use std::time::Duration;

fn main() -> std::io::Result<()> {
    let socket = UnixStream::connect("/tmp/sock")?;
    let result = socket.set_read_timeout(Some(Duration::new(0, 0)));
    let err = result.unwrap_err();
    assert_eq!(err.kind(), io::ErrorKind::InvalidInput);
    Ok(())
}

pub fn set_write_timeout(&self, dur: Option<Duration>) -> Result<()>

🔬This is a nightly-only experimental API. (windows_unix_domain_sockets #150487)

Sets the write timeout for the socket.

If the provided value is None, then write calls will block indefinitely. An Err is returned if the zero Duration is passed to this method.

Examples

#![feature(windows_unix_domain_sockets)]
use std::os::windows::net::UnixStream;
use std::time::Duration;

fn main() -> std::io::Result<()> {
    let socket = UnixStream::connect("/tmp/sock")?;
    socket.set_write_timeout(Some(Duration::new(1, 0)))
        .expect("Couldn't set write timeout");
    Ok(())
}

An Err is returned if the zero Duration is passed to this method:

#![feature(windows_unix_domain_sockets)]
use std::io;
use std::os::windows::net::UnixStream;
use std::time::Duration;

fn main() -> std::io::Result<()> {
    let socket = UnixStream::connect("/tmp/sock")?;
    let result = socket.set_write_timeout(Some(Duration::new(0, 0)));
    let err = result.unwrap_err();
    assert_eq!(err.kind(), io::ErrorKind::InvalidInput);
    Ok(())
}

pub fn shutdown(&self, how: Shutdown) -> Result<()>

🔬This is a nightly-only experimental API. (windows_unix_domain_sockets #150487)

Shuts down the read, write, or both halves of this connection.

This function will cause all pending and future I/O calls on the specified portions to immediately return with an appropriate value (see the documentation of Shutdown).

Examples

#![feature(windows_unix_domain_sockets)]
use std::os::windows::net::UnixStream;
use std::net::Shutdown;

fn main() -> std::io::Result<()> {
    let socket = UnixStream::connect("/tmp/sock")?;
    socket.shutdown(Shutdown::Both).expect("shutdown function failed");
    Ok(())
}

pub fn take_error(&self) -> Result<Option<Error>>

🔬This is a nightly-only experimental API. (windows_unix_domain_sockets #150487)

Returns the value of the SO_ERROR option.

Examples

#![feature(windows_unix_domain_sockets)]
use std::os::windows::net::UnixStream;

fn main() -> std::io::Result<()> {
    let socket = UnixStream::connect("/tmp/sock")?;
    if let Ok(Some(err)) = socket.take_error() {
        println!("Got error: {err:?}");
    }
    Ok(())
}

pub fn try_clone(&self) -> Result<UnixStream>

🔬This is a nightly-only experimental API. (windows_unix_domain_sockets #150487)

Creates a new independently owned handle to the underlying socket.

The returned UnixStream is a reference to the same stream that this object references. Both handles will read and write the same stream of data, and options set on one stream will be propagated to the other stream.

Examples

#![feature(windows_unix_domain_sockets)]
use std::os::windows::net::UnixStream;

fn main() -> std::io::Result<()> {
    let socket = UnixStream::connect("/tmp/sock")?;
    let sock_copy = socket.try_clone().expect("Couldn't clone socket");
    Ok(())
}

pub fn write_timeout(&self) -> Result<Option<Duration>>

🔬This is a nightly-only experimental API. (windows_unix_domain_sockets #150487)

Returns the write timeout of this socket.

Examples

#![feature(windows_unix_domain_sockets)]
use std::os::windows::net::UnixStream;
use std::time::Duration;

fn main() -> std::io::Result<()> {
    let socket = UnixStream::connect("/tmp/sock")?;
    socket.set_write_timeout(Some(Duration::new(1, 0)))
        .expect("Couldn't set write timeout");
    assert_eq!(socket.write_timeout()?, Some(Duration::new(1, 0)));
    Ok(())
}
