[−][src]Function bmrng::channel_with_timeout
pub fn channel_with_timeout<Req, Res>(
buffer: usize,
timeout_duration: Duration
) -> (RequestSender<Req, Res>, RequestReceiver<Req, Res>)
Creates a bounded mpsc request-response channel for communicating between asynchronous tasks with backpressure and a request timeout
Panics
Panics if the buffer capacity is 0, just like the Tokio MPSC channel
Examples
use tokio::time::{Duration, sleep}; #[tokio::main] async fn main() { let (tx, mut rx) = bmrng::channel_with_timeout::<i32, i32>(100, Duration::from_millis(100)); tokio::spawn(async move { match rx.recv().await { Ok((input, mut responder)) => { sleep(Duration::from_millis(200)).await; let res = responder.respond(input * input); assert_eq!(res.is_ok(), true); } Err(err) => { println!("all request senders dropped"); } } }); let response = tx.send_receive(8).await; assert_eq!(response, Err(bmrng::error::RequestError::<i32>::RecvTimeoutError)); }
