Functions

func CacheCallback

func CacheCallback[F ~func(A) T, KF func(A) K, C ~func(K, func() func() T) func() T, A any, K comparable, T any](kf KF, getOrCreate C) func(F) F

CacheCallback converts a unary function into a unary function that caches the value depending on the parameter

func ContramapMemoize

func ContramapMemoize[F ~func(A) T, KF func(A) K, A any, K comparable, T any](kf KF) func(F) F

ContramapMemoize converts a unary function into a unary function that caches the value depending on the parameter

func Memoize

func Memoize[F ~func(K) T, K comparable, T any](f F) F

Memoize converts a unary function into a unary function that caches the value depending on the parameter

func Switch

func Switch[HF ~func(T) R, N ~map[K]HF, KF ~func(T) K, K comparable, T, R any](kf KF, n N, d HF) HF

Switch applies a handler to different cases. The handers are stored in a map. A key function extracts the case from a value.
