Struct browser_window::DelegateFuture[−][src]

pub struct DelegateFuture<'a, H, R> where
    R: Send,  { /* fields omitted */ }

Expand description

This future executes a closure on the GUI thread and returns the result.

Trait Implementations

[src]

impl<'a, H, R> Future for DelegateFuture<'a, H, R> where
H: HasAppHandle + Clone + 'static,
R: Send + 'static,

type Output = Result<R, DelegateError>

The type of value produced on completion.

[src]

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

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

[src]

impl<'a, H, R> Send for DelegateFuture<'a, H, R> where
R: Send,

Safety

DelegateFuture by itself is not send. This is because we keep a handle H, which is not necessarily Send. However, because the closure only executes on the GUI thread, and because the handle is only provided to the closure that will be executed on the GUI thread, this should be fine.
