Provided methods

fn map<F, T, Fut>(self, f: F) -> Map<T> where
    F: FnMut(Self::Item) -> Fut + Send + Sync + Copy + 'static,
    T: Send + 'static,
    Fut: Future<Output = T> + Send, 

Applies f to each item of this stream in parallel, producing a new stream with the results.

fn next(&mut self) -> NextFuture<Self>

Applies f to each item of this stream in parallel, producing a new stream with the results.

fn take(self, n: usize) -> Take<Self> where
    Self: Sized, 

Creates a stream that yields its first n elements.

fn for_each<F, Fut>(self, f: F) -> ForEach where
    F: FnMut(Self::Item) -> Fut + Send + Sync + Copy + 'static,
    Fut: Future<Output = ()> + Send, 

Applies f to each item of this stream in parallel.
