Struct PromisesUnordered

pub struct PromisesUnordered<T>(/* private fields */);

Expand description

Represents a collection of zero or more concurrent operations.

Similar to [futures::stream::FuturesUnordered], this type supports awaiting more than one Promises concurrently.

Implementations§

§

impl<T> PromisesUnordered<T>
where T: 'static,

pub fn new() -> PromisesUnordered<T>

Create a new PromisesUnordered with no entries.

pub fn push(&mut self, promise: Promise<T>)

Add the specified Promise to this collection.

pub async fn next( &mut self, store: impl AsContextMut<Data = U>, ) -> Result<Option<T>, Error>
where U: Send,

Get the next result from this collection, if any.
