Trait InvalidateWhenEx 

pub trait InvalidateWhenEx<T> {
    // Required method
    fn invalidate_when<U: 'static>(
        &self,
        invalidate: Rc<dyn IObservable<U>>,
    ) -> Rc<dyn IObservable<T>>;
}

The invalidation of an aggregating sequence (InvalidateWhen), for every sequence.

Required Methods

fn invalidate_when<U: 'static>( &self, invalidate: Rc<dyn IObservable<U>>, ) -> Rc<dyn IObservable<T>>

The sequence, subscribed again each time invalidate notifies, without repeating a value: used when an item changes inline, so that an aggregation is computed again (InvalidateWhen(IObservable<Unit>) and InvalidateWhen<T, TTrigger>(IObservable<TTrigger?>), which are one method: the trigger’s values are not read).

Dyn Compatibility

This trait is not dyn compatible.

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