Struct ListenOptions 

pub struct ListenOptions { /* private fields */ }

Options set on a listening socket before bind and listen.

use net_io::{ListenOptions, TcpListener};
let options = ListenOptions::new().backlog(4096).reuse_port(cfg!(target_os = "linux"));
let listener = TcpListener::bind_with("127.0.0.1:0", options)?;
println!("effective backlog {:?}", listener.info().backlog);

Implementations

impl ListenOptions

pub fn new() -> ListenOptions

Backlog 1,024; reuse address on Unix, exclusive address use on Windows; IPv6-only; TCP_NODELAY on accepted sockets.

pub fn backlog(self, n: u32) -> ListenOptions

The listen backlog (capped by the OS; the effective value is in ListenerInfo).

pub fn reuse_address(self, on: bool) -> ListenOptions

Unix: SO_REUSEADDR. Windows: false = SO_EXCLUSIVEADDRUSE, true = SO_REUSEADDR.

pub fn reuse_port(self, on: bool) -> ListenOptions

SO_REUSEPORT (Unsupported on Windows).

pub fn ipv6_only(self, on: bool) -> ListenOptions

IPV6_V6ONLY for IPv6 addresses (on by default; decision D-026).

pub fn send_buffer(self, bytes: u32) -> ListenOptions

SO_SNDBUF on the listener (before listen).

pub fn receive_buffer(self, bytes: u32) -> ListenOptions

SO_RCVBUF on the listener (before listen, so window scaling is negotiated).

pub fn tcp_options(self, options: TcpOptions) -> ListenOptions

Options applied to every accepted socket.
