Feature gate: #![feature(tcp_linger)]

This is a tracking issue for the TcpStream::linger and TcpStream::set_linger methods that get/set the SO_LINGER option on the socket. Behavior works as expected on both Unix and Windows.

Public API

impl TcpStream {
    pub fn set_linger(&self, linger: Option<Duration>) -> io::Result<()>;
    pub fn linger(&self) -> io::Result<Option<Duration>>;
}

Steps / History

• Implementation: Add TcpStream::set_linger and TcpStream::linger #88495
• Final comment period (FCP)
• Stabilization PR

Unresolved Questions

• Should enabling lingering and setting the duration be split out into two operations?
