Trait Handler 

pub trait Handler<__Context__, Code, Input>: IsProviderFor<HandlerComponent, __Context__, (Code, Input)>
where
    __Context__: HasErrorType,
{
    type Output;

    // Required method
    fn handle(
        __context__: &__Context__,
        _tag: PhantomData<Code>,
        input: Input,
    ) -> impl Future<Output = Result<Self::Output, __Context__::Error>>;
}

Required Associated Types

type Output

Required Methods

fn handle( __context__: &__Context__, _tag: PhantomData<Code>, input: Input, ) -> impl Future<Output = Result<Self::Output, __Context__::Error>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
