Functions ¶

func CacheCallback ¶

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

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 SingleElementCache ¶

func SingleElementCache[
	LLT ~func() LT,
	K comparable,
	LT ~func() T,
	T any,
]() func(K, LLT) LT

SingleElementCache is a cache with a capacity of a single element

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.
