Enum actix_web::dev::Server [−][src]
Expand description
General purpose TCP server that runs services receiving Tokio TcpStream
s.
Handles creating worker threads, restarting faulted workers, connection accepting, and back-pressure logic.
Creates a worker per CPU core (or the number specified in ServerBuilder::workers
) and
distributes connections with a round-robin strategy.
The Server must be awaited to process stop commands and listen for OS signals. It will resolve when the server has fully shut down.
Shutdown Signals
On UNIX systems, SIGQUIT
will start a graceful shutdown and SIGTERM
or SIGINT
will start a
forced shutdown. On Windows, a Ctrl-C signal will start a forced shutdown.
A graceful shutdown will wait for all workers to stop first.
Examples
The following is a TCP echo server. Test using telnet 127.0.0.1 8080
.
use std::io;
use actix_rt::net::TcpStream;
use actix_server::Server;
use actix_service::{fn_service, ServiceFactoryExt as _};
use bytes::BytesMut;
use tokio::io::{AsyncReadExt as _, AsyncWriteExt as _};
#[actix_rt::main]
async fn main() -> io::Result<()> {
let bind_addr = ("127.0.0.1", 8080);
Server::build()
.bind("echo", bind_addr, move || {
fn_service(move |mut stream: TcpStream| {
async move {
let mut size = 0;
let mut buf = BytesMut::new();
loop {
match stream.read_buf(&mut buf).await {
// end of stream; bail from loop
Ok(0) => break,
// write bytes back to stream
Ok(bytes_read) => {
stream.write_all(&buf[size..]).await.unwrap();
size += bytes_read;
}
Err(err) => {
eprintln!("Stream Error: {:?}", err);
return Err(());
}
}
}
Ok(())
}
})
.map_err(|err| eprintln!("Service Error: {:?}", err))
})?
.run()
.await
}
