Struct FuturesSet 

pub struct FuturesSet<O> { /* private fields */ }

Represents a list of [Future]s.

Each future must finish within the specified time and the list never outgrows its capacity.

Implementations

impl<O> FuturesSet<O>

pub fn new( make_delay: impl Fn() -> Delay + Send + Sync + 'static, capacity: usize, ) -> Self

impl<O> FuturesSet<O>

where O: 'static,

pub fn try_push<F>( &mut self, future: F, ) -> Result<(), Pin<Box<dyn AnyFuture<Output = O> + Send>>>

where F: AnyFuture<Output = O>,

Push a future into the list.

This method adds the given future to the list. If the length of the list is equal to the capacity, this method returns a error that contains the passed future. In that case, the future is not added to the set.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn poll_ready_unpin(&mut self, cx: &mut Context<'_>) -> Poll<()>

pub fn poll_unpin(&mut self, cx: &mut Context<'_>) -> Poll<Result<O, Timeout>>

pub fn iter_of_type<T>(&self) -> impl Iterator<Item = Pin<&T>>

where T: 'static,

Returns an iterator over all futures of type T pushed via FuturesSet::try_push. This iterator returns futures in an arbitrary order, which may change.

If downcasting a future to T fails it will be skipped in the iterator.

pub fn iter_mut_of_type<T>(&mut self) -> impl Iterator<Item = Pin<&mut T>>

where T: 'static,

Returns an iterator with mutable access over all futures of type T pushed via FuturesSet::try_push. This iterator returns futures in an arbitrary order, which may change.

If downcasting a future to T fails it will be skipped in the iterator.
