Struct IncomingStream 

pub struct IncomingStream { /* private fields */ }

A stream of incoming connections.

IncomingStream::bind is the primary entrypoint for constructing a new IncomingStream.

Incoming connections will be usually passed to a Server instance to be handled. Check out Server::bind or Server::listen for more information.

Implementations

impl IncomingStream

pub async fn bind(addr: SocketAddr) -> Result<Self>

Create a new IncomingStream by binding to a socket address.
The socket will be configured to be non-blocking and reuse the address.

Example

use std::net::SocketAddr;
use pavex::server::{IncomingStream, Server};

let addr = SocketAddr::from(([127, 0, 0, 1], 8080));
let incoming = IncomingStream::bind(addr).await?;

Custom configuration

If you want to customize the options set on the socket, you can build your own TcpListener using [socket2::Socket] and then convert it into an IncomingStream via TryFrom::try_from.
There’s only one option you can’t change: the socket will always be set to non-blocking mode.

use std::net::SocketAddr;
use socket2::Domain;
use pavex::server::{IncomingStream, Server};

let addr = SocketAddr::from(([127, 0, 0, 1], 8080));

let socket = socket2::Socket::new(
   Domain::for_address(addr),
   socket2::Type::STREAM,
   Some(socket2::Protocol::TCP),
)
.expect("Failed to create a socket");
socket.set_reuse_address(true)?;
socket.set_nonblocking(true)?;
socket.bind(&addr.into())?;
// We customize the backlog setting!
socket.listen(2048_i32)?;

let listener = std::net::TcpListener::from(socket);
let incoming: IncomingStream = listener.try_into()?;

pub fn local_addr(&self) -> Result<SocketAddr>

Returns the address that this IncomingStream is bound to.

pub async fn accept(&self) -> Result<(TcpStream, SocketAddr)>

Accepts a new incoming connection from the underlying listener.

This function will yield once a new TCP connection is established. When established, the corresponding [TcpStream] and the remote peer’s address will be returned.

Example

use pavex::server::IncomingStream;
use std::net::SocketAddr;

let address = SocketAddr::from(([127, 0, 0, 1], 8080));
let incoming = IncomingStream::bind(address).await?;

match incoming.accept().await {
    Ok((_socket, addr)) => println!("new client: {:?}", addr),
    Err(e) => println!("couldn't get client: {:?}", e),
}

Trait Implementations

impl From<TcpListener> for IncomingStream

fn from(v: TcpListener) -> Self

Converts to this type from the input type.

impl TryFrom<TcpListener> for IncomingStream

type Error = Error

The type returned in the event of a conversion error.

fn try_from(v: TcpListener) -> Result<Self>

Performs the conversion.
