[−][src]Struct multiqueue2::MPMCSender
This class is the sending half of the mpmc 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::mpmc_queue(4); let mut handles = vec![]; for i in 0..2 { // or n let consumer = recv.clone(); handles.push(thread::spawn(move || { for val in consumer { println!("Consumer {} got {}", i, val); } })); } // 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 // Consumer 1 got 2 // Consumer 0 got 0 // Consumer 0 got 1 // etc
Methods
impl<T> MPMCSender<T>
[src]
pub fn try_send(&self, val: T) -> Result<(), TrySendError<T>>
[src]
Tries to send a value into the queue
If there is no space, returns Err(TrySendError::Full(val))
If there are no readers, returns Err(TrySendError::Disconnected(val))
pub fn unsubscribe(self)
[src]
Removes this writer from the queue
