Struct TrackerExecutor

pub struct TrackerExecutor<E> { /* private fields */ }

Track running tasks.

Note that there is no guarantee that the runtime would drop the future after it is done; therefore, this should only be used for purely approx statistics and not actual numbers. Additionally, it does not track any tasks spawned directly by the runtime but only by Executor::spawn through this struct.

Implementations

impl<E: Executor> TrackerExecutor<E>

pub fn new(executor: E) -> Self

pub fn count(&self) -> usize

Number of active tasks.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<E: Executor> Executor for TrackerExecutor<E>

fn spawn<F>(&self, future: F) -> JoinHandle<F::Output>

where F: Future + Send + 'static, F::Output: Send + 'static,

Spawns a new asynchronous task in the background, returning a Future JoinHandle for it.

fn spawn_abortable<F>(&self, future: F) -> AbortableJoinHandle<F::Output>

where F: Future + Send + 'static, F::Output: Send + 'static,

Spawns a new asynchronous task in the background, returning an abortable handle that will cancel the task once the handle is dropped.

fn dispatch<F>(&self, future: F)

where F: Future + Send + 'static, F::Output: Send + 'static,

Spawns a new asynchronous task in the background without an handle. Basically the same as Executor::spawn.

fn spawn_coroutine<T, F, Fut>(&self, f: F) -> CommunicationTask<T>

where F: FnMut(Receiver<T>) -> Fut, Fut: Future<Output = ()> + Send + 'static,

Spawns a new asynchronous task that accepts messages to the task using channels. This function returns a handle that allows sending a message, or if there is no reference to the handle at all (in other words, all handles are dropped), the task would be aborted.

fn spawn_coroutine_with_context<T, F, C, Fut>( &self, context: C, f: F, ) -> CommunicationTask<T>

where F: FnMut(C, Receiver<T>) -> Fut, Fut: Future<Output = ()> + Send + 'static,

Spawns a new asynchronous task with provided context that accepts messages to the task using channels. This function returns a handle that allows sending a message, or if there is no reference to the handle at all (in other words, all handles are dropped), the task would be aborted.

fn spawn_unbounded_coroutine<T, F, Fut>( &self, f: F, ) -> UnboundedCommunicationTask<T>

where F: FnMut(UnboundedReceiver<T>) -> Fut, Fut: Future<Output = ()> + Send + 'static,

Spawns a new asynchronous task that accepts messages to the task using channels. This function returns a handle that allows sending a message, or if there is no reference to the handle at all (in other words, all handles are dropped), the task would be aborted.

fn spawn_unbounded_coroutine_with_context<T, F, C, Fut>( &self, context: C, f: F, ) -> UnboundedCommunicationTask<T>

where F: FnMut(C, UnboundedReceiver<T>) -> Fut, Fut: Future<Output = ()> + Send + 'static,

Spawns a new asynchronous task with provided context that accepts messages to the task using channels. This function returns a handle that allows sending a message, or if there is no reference to the handle at all (in other words, all handles are dropped), the task would be aborted.
