-/// An unbounded set of streams
-///
-/// This "combinator" provides the ability to maintain a set of streams
-/// and drive them all to completion.
-///
-/// Streams are pushed into this set and their realized values are
-/// yielded as they become ready. Streams will only be polled when they
-/// generate notifications. This allows to coordinate a large number of streams.
-///
-/// Note that you can create a ready-made `SelectAll` via the
-/// `select_all` function in the `stream` module, or you can start with an
-/// empty set with the `SelectAll::new` constructor.
