Os-specific extensions for TcpStream
Required Methods§
sourcefn set_quickack(&self, quickack: bool) -> Result<()>
🔬This is a nightly-only experimental API. (tcp_quickack
#96256)
fn set_quickack(&self, quickack: bool) -> Result<()>
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
sourcefn quickack(&self) -> Result<bool>
🔬This is a nightly-only experimental API. (tcp_quickack
#96256)
fn quickack(&self) -> Result<bool>
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);
sourcefn set_deferaccept(&self, accept: u32) -> Result<()>
🔬This is a nightly-only experimental API. (tcp_deferaccept
#119639)
fn set_deferaccept(&self, accept: u32) -> Result<()>
tcp_deferaccept
#119639)A socket listener will be awakened solely when data arrives.
The accept
argument set the delay in seconds until the
data is available to read, reducing the number of short lived
connections without data to process.
Contrary to other platforms SO_ACCEPTFILTER
feature equivalent, there is
no necessity to set it after the listen
call.
See man 7 tcp
§Examples
#![feature(tcp_deferaccept)]
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_deferaccept(1).expect("set_deferaccept call failed");
sourcefn deferaccept(&self) -> Result<u32>
🔬This is a nightly-only experimental API. (tcp_deferaccept
#119639)
fn deferaccept(&self) -> Result<u32>
tcp_deferaccept
#119639)Gets the accept delay value (in seconds) of the TCP_DEFER_ACCEPT
option.
For more information about this option, see TcpStreamExt::set_deferaccept
.
§Examples
#![feature(tcp_deferaccept)]
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_deferaccept(1).expect("set_deferaccept call failed");
