Struct WorkerPool 

pub struct WorkerPool { /* private fields */ }

A fixed-size pool of persistent worker threads.

Submit 'static jobs with submit; they run on the next free worker. The pool joins all workers on Drop, so a scheduler simply holds it as a field and lets RAII shut it down.

Implementations

impl WorkerPool

pub fn new(size: usize) -> Self

Spawns a pool of size worker threads (at least one).

pub fn thread_count(&self) -> usize

Number of worker threads in the pool.

pub fn submit<F>(&self, job: F)

where F: FnOnce() + Send + 'static,

Submits a job to run on the next free worker.

Best-effort: if the pool is mid-shutdown (all workers gone) the job is dropped rather than run. During normal operation the send always succeeds.

Trait Implementations

impl Drop for WorkerPool

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
