Implementations§

Source§

impl<R, T, U> GroupByReducerBAsync<R, T, U>
where R: Reducer<U>,

Source

pub fn new(f: R) -> Self

Constructs a new GroupByReducerBAsync.

Trait Implementations§

Source§

impl<R, T, U> Sink<IndexMap<T, U>> for GroupByReducerBAsync<R, T, U>
where R: Reducer<U> + Clone, T: Eq + Hash,

Source§

type Done = IndexMap<T, <R as Reducer<U>>::Done>

Source§

fn poll_forward( self: Pin<&mut Self>, cx: &mut Context<'_>, stream: Pin<&mut impl Stream<Item = IndexMap<T, U>>>, ) -> Poll<Self::Done>

Returns Poll::Ready when a) it can’t accept any more elements from stream and b) all accepted elements have been fully processed. By convention, stream yielding None typically triggers (a).
