Struct wayland_commons::filter::Filter [−][src]
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.
Implementations
impl<E> Filter<E>[src]
pub fn new<F: FnMut(E, &Filter<E>, DispatchData<'_>) + 'static>(
f: F
) -> Filter<E>[src]
f: F
) -> Filter<E>
Create a new filter from given closure
pub fn send(&self, evt: E, data: DispatchData<'_>)[src]
Send a message to this filter
