Description

Prisms and Traversals for the Can datatype.

Synopsis

Prisms

_Non :: Prism' (Can a b) () Source #

A Prism' selecting the Non constructor.

Note: cannot change type.

_One :: Prism' (Can a b) a Source #

A Prism' selecting the One constructor.

Note: cannot change type.

_Eno :: Prism' (Can a b) b Source #

A Prism' selecting the Eno constructor.

Note: cannot change type.

_Two :: Prism' (Can a b) (a, b) Source #

A Prism' selecting the Two constructor.

Note: cannot change type.

Traversals

oneing :: Traversal (Can a c) (Can b c) a b Source #

A Traversal of the first parameter, suitable for use with Control.Lens.

enoing :: Traversal (Can a b) (Can a c) b c Source #

A Traversal of the second parameter, suitable for use with Control.Lens.

twoed :: Traversal' (Can a b) (a, b) Source #

A Traversal of the pair, suitable for use with Control.Lens.

twoing :: Traversal (Can a a) (Can b b) a b Source #

A Traversal of the pair ala both, suitable for use with Control.Lens.

Swapped Can Source #
