Struct SoftCycleListener 

pub struct SoftCycleListener<'a, T: Payload> { /* private fields */ }

Future that completes when a notification from the associated controller is observed.

Returned by SoftCycleController::listener. Resolves to Ok(payload) when a notification is observed. If the controller is already notified when the listener is created or first polled, it may complete immediately with that payload. If multiple notify/clear cycles occur after the listener is created, it returns one of those payloads (no guarantee of returning the earliest or latest). See the crate-level documentation for full completion guarantees.

Trait Implementations

type Output = Result<T, ()>

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
