Struct Executor 

pub struct Executor(/* private fields */);

Rust async executor

This is the main interface to the runtime, besides the Worker struct. What isn’t covered by that struct is covered here.

Implementations

impl Executor

pub fn new(thread_count: usize) -> Self

Create a new executor

This creates a new executor with the specified number of threads.

pub fn spawn_task<T>( &self, future: impl Future<Output = T> + Send + 'static, ) -> Option<AsyncTask<'static, T>>

where T: Send + Debug + 'static,

Spawn a task on the executor

Create a new task on the main worker and start it running.

pub fn create_task<T>( &self, future: impl Future<Output = T> + Send + 'static, ) -> Option<AsyncTask<'static, T>>

where T: Send + Debug + 'static,

Create a task on the executor

Create a task on the main worker

pub fn timer(&self, duration: Duration) -> impl Future<Output = Instant>

Pause execution for the specified duration

This starts a timer on the root worker.

pub fn start_task<T>(&self, task: &AsyncTask<'_, T>)

Start a paused task

This starts a paused task on the executor.

pub fn worker_count(&self) -> usize

Worker cardinality

This returns the number of workers on the executor.

pub fn new_worker(&self) -> Worker

Create a new worker

This creates a new worker on the executor.

pub fn root_worker(&self) -> Worker

Root worker

This returns the root worker on the executor.
