Struct calloop::Dispatcher
source · pub struct Dispatcher<'a, S, Data>(/* private fields */);
Expand description
An event source with its callback.
The Dispatcher
can be registered in an event loop.
Use the as_source_{ref,mut}
functions to interact with the event source.
Use into_source_inner
to get the event source back.
Implementations§
source§impl<'a, S, Data> Dispatcher<'a, S, Data>where
S: EventSource + 'a,
impl<'a, S, Data> Dispatcher<'a, S, Data>where
S: EventSource + 'a,
sourcepub fn as_source_ref(&self) -> Ref<'_, S>
pub fn as_source_ref(&self) -> Ref<'_, S>
Returns an immutable reference to the event source.
§Panics
Has the same semantics as RefCell::borrow()
.
The dispatcher being mutably borrowed while its events are dispatched, this method will panic if invoked from within the associated dispatching closure.
sourcepub fn as_source_mut(&self) -> RefMut<'_, S>
pub fn as_source_mut(&self) -> RefMut<'_, S>
Returns a mutable reference to the event source.
§Panics
Has the same semantics as RefCell::borrow_mut()
.
The dispatcher being mutably borrowed while its events are dispatched, this method will panic if invoked from within the associated dispatching closure.
sourcepub fn into_source_inner(self) -> S
pub fn into_source_inner(self) -> S
Consumes the Dispatcher and returns the inner event source.
§Panics
Panics if the Dispatcher
is still registered.
