Description
Each
class Each s t a b | s -> a, t -> b, s b -> t, t a -> s where Source #
Extract
each
element of a (potentially monomorphic) container.
Notably, when applied to a tuple, this generalizes
both
to arbitrary homogeneous tuples.
>>>
(1,2,3) & each *~ 10
(10,20,30)
It can also be used on monomorphic containers like
Text
or
ByteString
.
>>>
over each Char.toUpper ("hello"^.Text.packed)
"HELLO"
>>>
("hello","world") & each.each %~ Char.toUpper
("HELLO","WORLD")
