Struct async_select_all::SelectAll

pub struct SelectAll<F: Future> { /* fields omitted */ }

An unbounded set of futures.

Implementations

impl<F: Future> SelectAll<F>

pub fn new() -> Self

Constructs a new, empty SelectAll. The returned SelectAll does not contain any futures.

pub fn len(&self) -> usize

Returns the number of futures contained in the set. This represents the total number of in-flight futures.

pub fn is_empty(&self) -> bool

Returns true if the set contains no futures.

pub fn push(&mut self, future: F)

Push a future into the set. This function submits the given future to the set for managing. This function will not call poll on the submitted future. The caller must ensure that SelectAll::select is called in order to receive task notifications.

pub async fn select<'_>(&'_ mut self) -> F::Output

Select over a list of futures.

Upon completion the item resolved will be returned.

There are no guarantees provided on the order of the list with the remaining futures. They might be swapped around, reversed, or completely random.

Panics

This function will panic if the SelectAll specified contains no items.
