pub struct Filter<E> { /* private fields */ }
Expand description

An event filter

Can be used in wayland-client and wayland-server to aggregate messages from different objects into the same closure.

You need to provide it a closure of type FnMut(E, &Filter<E>), which will be called any time a message is sent to the filter via the send(..) method. Your closure also receives a handle to the filter as argument, so that you can use it from within the callback (to assign new wayland objects to this filter for example).

The Filter can be cloned, and all clones send messages to the same closure. However it is not threadsafe.

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more
