Functions ¶

func And ¶

func And[A any](second func(A) bool) func(func(A) bool) func(A) bool

And creates a predicate that combines other predicates via &&

func ContraMap ¶

func ContraMap[A, B any](f func(B) A) func(func(A) bool) func(B) bool

ContraMap creates a predicate from an existing predicate given a mapping function

func MonoidAll ¶

func MonoidAll[A any]() S.Semigroup[func(A) bool]

MonoidAll combines predicates via &&

func MonoidAny ¶

func MonoidAny[A any]() S.Semigroup[func(A) bool]

MonoidAny combines predicates via ||

func Not ¶

func Not[A any](predicate func(A) bool) func(A) bool

func Or ¶

func Or[A any](second func(A) bool) func(func(A) bool) func(A) bool

Or creates a predicate that combines other predicates via ||

func SemigroupAll ¶

func SemigroupAll[A any]() S.Semigroup[func(A) bool]

SemigroupAll combines predicates via &&

func SemigroupAny ¶

func SemigroupAny[A any]() S.Semigroup[func(A) bool]

SemigroupAny combines predicates via ||
