Os-specific extensions for `TcpStream`

## Required Methods§

source

#### fn set_quickack(&self, quickack: bool) -> Result<()>

🔬This is a nightly-only experimental API. (`tcp_quickack` #96256)

Enable or disable `TCP_QUICKACK`.

This flag causes Linux to eagerly send ACKs rather than delaying them. Linux may reset this flag after further operations on the socket.

See `man 7 tcp` and TCP delayed acknowledgement for more information.

##### Examples

    #![feature(tcp_quickack)]
    use std::net::TcpStream;
    use std::os::linux::net::TcpStreamExt;

    let stream = TcpStream::connect("127.0.0.1:8080")
            .expect("Couldn't connect to the server...");
    stream.set_quickack(true).expect("set_quickack call failed");

#### fn quickack(&self) -> Result<bool>

🔬This is a nightly-only experimental API. (`tcp_quickack` #96256)

Gets the value of the `TCP_QUICKACK` option on this socket.

For more information about this option, see `TcpStreamExt::set_quickack`.

##### Examples

    #![feature(tcp_quickack)]
    use std::net::TcpStream;
    use std::os::linux::net::TcpStreamExt;

    let stream = TcpStream::connect("127.0.0.1:8080")
            .expect("Couldn't connect to the server...");
    stream.set_quickack(true).expect("set_quickack call failed");
    assert_eq!(stream.quickack().unwrap_or(false), true);
