Struct SignalFuture

pub struct SignalFuture<R: InParamTuple + IntoDynamicSend>(/* private fields */);

Available on since_api="4.2" only.

The panicking counter part to the FallibleSignalFuture.

This future works in the same way as FallibleSignalFuture, but panics when the signal object is freed, instead of resolving to a Result::Err.

Panics

• If the signal object is freed before the signal has been emitted.
• If one of the signal arguments is !Send, but the signal was emitted on a different thread.
• The future’s Drop implementation can cause a non-unwinding panic in rare cases, should the signal object be freed at the same time as the future is dropped. Make sure to keep signal objects alive until there are no pending futures anymore.

Trait Implementations

impl<R: InParamTuple + IntoDynamicSend> Future for SignalFuture<R>

type Output = R

The type of value produced on completion.

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.
