[−][src]Struct wait_for_me::CountDownLatch
A syncronization primitive that allow one or more tasks to wait untile the given counter reaches zero. This is an async port of CountDownLatch in Java.
Methods
impl CountDownLatch
[src]
pub fn new(count: usize) -> CountDownLatch
[src]
Creates a new CountDownLatch
with a given count.
pub async fn count<'_>(&'_ self) -> usize
[src]
Returns the current count.
pub fn wait(&self) -> impl Future<Output = ()>
[src]
Cause the current task to wait until the counter reaches zero
pub async fn wait_for<'_>(&'_ self, timeout: Duration) -> bool
[src]
Cause the current task to wait until the counter reaches zero with timeout.
If the specified timeout elapesed false
is retured. Otherwise true
.
pub async fn count_down<'_>(&'_ self)
[src]
Decrement the counter of one unit. If the counter reaches zero all the waiting tasks are released.
