[−][src]Struct multiqueue2::BroadcastSender
This class is the sending half of the broadcasting MultiQueue
. It supports both
single and multi consumer modes with competitive performance in each case.
It only supports nonblocking writes (the futures sender being an exception)
as well as being the conduit for adding new writers.
Examples
use std::thread; let (send, recv) = multiqueue2::broadcast_queue(4); let mut handles = vec![]; for i in 0..2 { // or n let cur_recv = recv.add_stream(); for j in 0..2 { let stream_consumer = cur_recv.clone(); handles.push(thread::spawn(move || { for val in stream_consumer { println!("Stream {} consumer {} got {}", i, j, val); } })); } // cur_recv is dropped here } // Take notice that I drop the reader - this removes it from // the queue, meaning that the readers in the new threads // won't get starved by the lack of progress from recv recv.unsubscribe(); for i in 0..10 { // Don't do this busy loop in real stuff unless you're really sure loop { if send.try_send(i).is_ok() { break; } } } drop(send); for t in handles { t.join(); } // prints along the lines of // Stream 0 consumer 1 got 2 // Stream 0 consumer 0 got 0 // Stream 1 consumer 0 got 0 // Stream 0 consumer 1 got 1 // Stream 1 consumer 1 got 1 // Stream 1 consumer 0 got 2 // etc
