Expand description
A variant on Producer
which does not know its exact length or
cannot represent it in a usize
. These producers act like
ordinary producers except that they cannot be told to split at a
particular point. Instead, you just ask them to split ‘somewhere’.
(In principle, Producer
could extend this trait; however, it
does not because to do so would require producers to carry their
own length with them.)
