[−][src]Struct lifeline::barrier::BarrierReceiver
A receiver for a Barrier channel.
The barrier channel is a variant of a oneshot channel, where a Barrier sender acts as a synchronization fence.
The receiver implements Future and lifeline::Receiver, and resolves when the barrier sender is released or dropped
Example
use lifeline::barrier::*; #[derive(Debug, Clone, Default)] struct Message {} async fn run() { let (_tx, rx) = barrier::<Message>(); drop(_tx); rx.await; }
Implementations
impl<T: Clone + Default + Sync> BarrierReceiver<T>[src]
pub async fn recv(&self) -> T[src]
Returns when the associated barrier has been dropped.
Equivalent to self.await or self.clone().await
