Trait CallbackRef

pub trait CallbackRef<T: ?Sized> {
    // Required method
    fn callback_ref(&mut self, payload: &T);

    // Provided method
    fn into_callback(self) -> impl Callback<T>
       where Self: Sized,
             T: Sized { ... }
}

Used by push-oriented receivers to handle payload references as they are received.

See the compat module for Receive compatibility

Required Methods

fn callback_ref(&mut self, payload: &T)

Provided Methods

fn into_callback(self) -> impl Callback<T>

where Self: Sized, T: Sized,

Compatibility helper to convert any CallbackRef into a Callback when T is Sized.

This provides maximum compatibility when ownership of T is not required, as it allows users to always implement CallbackRef which can then be used in either circumstance.
