Struct Pool 

pub struct Pool<T> { /* private fields */ }

An unordered pool of futures.

Futures can be added to the pool, and removed from the pool as they resolve.

Note: This pool is not thread-safe and should not be used across threads without external synchronization.

Implementations

impl<T: Send> Pool<T>

pub fn len(&self) -> usize

Returns the number of futures in the pool.

pub fn is_empty(&self) -> bool

Returns true if the pool is empty.

pub fn push(&mut self, future: impl Future<Output = T> + Send + 'static)

Adds a future to the pool.

The future must be 'static and Send to ensure it can be safely stored and executed.

pub fn next_completed( &mut self, ) -> SelectNextSome<'_, FuturesUnordered<Pin<Box<dyn Future<Output = T> + Send>>>>

Returns a futures that resolves to the next future in the pool that resolves.

If the pool is empty, the future will never resolve.

pub fn cancel_all(&mut self)

Cancels all futures in the pool.

Excludes the dummy future.

Trait Implementations

impl<T: Send> Default for Pool<T>

fn default() -> Self

Returns the “default value” for a type.
