pub struct Zip<St1, St2> where
    St1: Stream,
    St2: Stream,  { /* fields omitted */ }

[−] Expand description

An adapter for merging the output of two streams.

The merged stream produces items from one or both of the underlying streams as they become available. Errors, however, are not merged: you get at most one error at a time.

Trait Implementations

impl<St1, St2> Unpin for Zip<St1, St2> where     St1: Unpin + Stream,     St2: Unpin + Stream,

impl<St1, St2> Debug for Zip<St1, St2> where     St1: Debug + Stream,     St2: Debug + Stream,     <St1 as Stream>::Item: Debug,     <St2 as Stream>::Item: Debug,

[+]

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

[−]

Formats the value using the given formatter.

impl<St1, St2> Stream for Zip<St1, St2> where     St1: Stream,     St2: Stream,

[+]

type Item = (<St1 as Stream>::Item, <St2 as Stream>::Item)

Values yielded by the stream.

fn poll_next(     self: PinMut<Zip<St1, St2>>,     cx: &mut Context ) -> Poll<Option<<Zip<St1, St2> as Stream>::Item>>

[−]

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.
