Struct ThreadPool

pub struct ThreadPool { /* private fields */ }

Thread pool for managing background tasks

The thread pool operates on “routines”, which are effectively closures called repeatedly by the thread pool until they return ControlFlow::Break.

To submit a task, pass it to ThreadPool::subscribe and store the received handle. To cancel a task, pass its handle to ThreadPool::unsubscribe.

Implementations

impl ThreadPool

pub fn subscribe<F>(&self, func: F) -> Result<Routine, Error>

where F: FnMut() -> ControlFlow<()> + Send + 'static,

Run a task in a background thread

pub fn unsubscribe(&self, routine: &Routine) -> Result<(), Error>

Cancel a task running in a background thread

Note: this does not kill a running task, only prevent it from being scheduled again

Trait Implementations

impl Debug for ThreadPool

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

Formats the value using the given formatter.
