Trait EventLoopRunReturnExt 

pub trait EventLoopRunReturnExt {
    type User;

    // Required method
    fn block_on_return<F, Fut>(
        &mut self,
        handler: F,
        fut: Fut,
    ) -> BlockOnReturnResult<Fut::Output>
       where F: FnMut(Event<'_, Self::User>, &Elwt<Signal<Self::User>>, &mut ControlFlow),
             Fut: Future;
}

An extension trait for EventLoop that allows one to block on a non-infinite future.

Required Associated Types

type User

Required Methods

fn block_on_return<F, Fut>( &mut self, handler: F, fut: Fut, ) -> BlockOnReturnResult<Fut::Output>

where F: FnMut(Event<'_, Self::User>, &Elwt<Signal<Self::User>>, &mut ControlFlow), Fut: Future,

Block on the provided future until either the loop exits or the future returns a value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
