Struct ordered_stream::JoinMultiple

source ·
pub struct JoinMultiple<C>(pub C);
Expand description

Join a collection of OrderedStreams.

This is similar to repeatedly using join() on all the streams in the contained collection. It is not optimized to avoid polling streams that are not ready, so it works best if the number of streams is relatively small.
