A Sink
is a special type of Fold
that does not accumulate any value,
but runs only effects. A Sink
has no state to maintain therefore can be a
bit more efficient than a Fold
with ()
as the state, especially when
Sink
s are composed with other operations. A Sink can be upgraded to a
Fold
, but a Fold
cannot be converted into a Sink.
