Description

Synopsis

class Each s t a b | s -> a, t -> b, s b -> t, t a -> s where
- each :: Traversal s t a b

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")
