Optics.IxSetter

Contents

Description

An IxSetter is an indexed version of a Setter. See the "Indexed optics" section of the overview documentation in the Optics module of the main optics package for more details on indexed optics.

Synopsis

Formation

type IxSetter i s t a b = Optic A_Setter (WithIx i) s t a b Source #

Type synonym for a type-modifying indexed setter.

type IxSetter' i s a = Optic' A_Setter (WithIx i) s a Source #

Type synonym for a type-preserving indexed setter.

Introduction

isets :: ((i -> a -> b) -> s -> t) -> IxSetter i s t a b Source #

Build an indexed setter from a function to modify the element(s).

Elimination

iover :: (Is k A_Setter, is `HasSingleIndex` i) => Optic k is s t a b -> (i -> a -> b) -> s -> t Source #

Apply an indexed setter as a modifier.

Computation

iover (isets f) ≡ f

Well-formedness

Additional introduction forms

imapped :: FunctorWithIndex i f => IxSetter i (f a) (f b) a b Source #

Indexed setter via the FunctorWithIndex class.

iover imappedimap

Additional elimination forms

iset :: (Is k A_Setter, is `HasSingleIndex` i) => Optic k is s t a b -> (i -> b) -> s -> t Source #

Apply an indexed setter.

iset o f ≡ iover o (i _ -> f i)

iset' :: (Is k A_Setter, is `HasSingleIndex` i) => Optic k is s t a b -> (i -> b) -> s -> t Source #

Apply an indexed setter, strictly.

iover' :: (Is k A_Setter, is `HasSingleIndex` i) => Optic k is s t a b -> (i -> a -> b) -> s -> t Source #

Apply an indexed setter as a modifier, strictly.

Subtyping

data A_Setter :: OpticKind Source #

Tag for a setter.
