Trait ActionCallback 

pub trait ActionCallback<Marker, Err> {
    type Input;
    type Output;

    // Required method
    fn call(
        &mut self,
        input: Self::Input,
    ) -> impl Future<Output = Result<Self::Output, Err>> + 'static;
}

Required Associated Types

type Input

type Output

Required Methods

fn call( &mut self, input: Self::Input, ) -> impl Future<Output = Result<Self::Output, Err>> + 'static

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.
