Struct bevy::tasks::CountdownEvent [−]
pub struct CountdownEvent { /* fields omitted */ }
Expand description
A counter that starts with an initial count n
. Once it is decremented n
times, it will be
“ready”. Call listen
to get a future that can be awaited.
Implementations
impl CountdownEvent
impl CountdownEvent
pub fn new(n: isize) -> CountdownEvent
pub fn new(n: isize) -> CountdownEvent
Creates a CountdownEvent
that must be decremented n
times for listeners to be
signalled
Get the number of times decrement must be called to trigger notifying all listeners
pub fn decrement(&self)
pub fn decrement(&self)
Decrement the counter by one. If this is the Nth call, trigger all listeners
Resets the counter. Any listens following this point will not be notified until decrement is called N times
pub async fn listen(&'_ self)
pub async fn listen(&'_ self)
Awaits decrement being called N times
