pub struct TaskPool<F: Future + 'static, const N: usize> { /* private fields */ }
Expand description

Raw storage that can hold up to N tasks of the same type.

This is essentially a [TaskStorage<F>; N].

Implementations§

source§

impl<F: Future + 'static, const N: usize> TaskPool<F, N>

source

pub const fn new() -> Self

Create a new TaskPool, with all tasks in non-spawned state.

source

pub fn spawn( &'static self, future: impl FnOnce() -> F ) -> SpawnToken<impl Sized>

Try to spawn a task in the pool.

See TaskStorage::spawn() for details.

This will loop over the pool and spawn the task in the first storage that is currently free. If none is free, a “poisoned” SpawnToken is returned, which will cause Spawner::spawn() to return the error.
