Trait Implementations

impl Clone for CurrentDispatcher

fn clone(&self) -> CurrentDispatcher

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl OnDispatcher for CurrentDispatcher

fn on_dispatcher<R>(&self, f: impl FnOnce(Option<DispatcherRef<'_>>) -> R) -> R

Runs the function f with a lifetime-bound DispatcherRef for this object’s dispatcher. If the dispatcher is no longer valid, the callback will be given None.

fn on_maybe_dispatcher<R, E>( &self, f: impl FnOnce(DispatcherRef<'_>) -> Result<R, E>, ) -> Result<R, E>

where E: From<Status>,

Helper version of OnDispatcher::on_dispatcher that translates an invalidated dispatcher handle into a [Status::BAD_STATE] error instead of giving the callback None.

fn spawn_task( &self, future: impl Future<Output = ()> + Send + 'static, ) -> Result<(), Status>

where Self: 'static,

Spawn an asynchronous task on this dispatcher. If this returns Ok then the task has successfully been scheduled and will run or be cancelled and dropped when the dispatcher shuts down.
