Struct FallibleSignalFuture

pub struct FallibleSignalFuture<R: InParamTuple + IntoDynamicSend> { /* private fields */ }

Available on since_api="4.2" only.

A future that tries to resolve as soon as the provided Godot signal was emitted.

The future might resolve to an error if the signal object is freed before the signal is emitted.

Panics

• 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> Drop for FallibleSignalFuture<R>

fn drop(&mut self)

Executes the destructor for this type.

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

type Output = Result<R, FallibleSignalFutureError>

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.
