Data.Validated

Definitions

data Validated : Type -> Type -> Type

  `Validated` is like an `Either` but accumulates all errors with semigroup operation.

Constructors:

Valid : a -> Validated e a

Invalid : e -> Validated e a

Hints:

Monoid e => Alternative (Validated e)

Semigroup e => Applicative (Validated e)

Bifoldable Validated

Bifunctor Validated

Bitraversable Validated

(DecEq e, DecEq a) => DecEq (Validated e a)

(Eq e, Eq a) => Eq (Validated e a)

Foldable (Validated e)

Functor (Validated e)

Injective Valid

Injective Invalid

Monoid e => Monoid (Validated e a)

Semigroup e => Semigroup (Validated e a)

(Show e, Show a) => Show (Validated e a)

Traversable (Validated e)

Uninhabited (Valid x = Invalid e)

Uninhabited (Invalid e = Valid x)

Semigroup e => Zippable (Validated e)

ValidatedL : Type -> Type -> Type

  Special case of `Validated` with a `List` as an error accumulator.
