Struct DelegateFutureFuture

pub struct DelegateFutureFuture<'a, R>where
    R: Send,
{ /* private fields */ }

Expand description

This future runs a future on the GUI thread and returns its output.

Trait Implementations§

impl<'a, R> Future for DelegateFutureFuture<'a, R>
where R: Send,

type Output = Result<R, DelegateError>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, ctx: &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. Read more

impl<'a, R> Send for DelegateFutureFuture<'a, R>
where R: Send,

§Safety

DelegateFutureFuture by itself is not send. This is because of ApplicationHandle. However, because the closure only executes on the GUI thread, and because this handle that is provided to the closure is something that will only be sent with the closure to the GUI thread, this should be fine.
