Trait EventLoopExt

pub trait EventLoopExt {
    type User;

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

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

Required Associated Types

type User

Required Methods

fn block_on<F, Fut>(self, handler: F, fut: Fut) -> !

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

Block on the provided future indefinitely.

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.
