reduce#

A simple map/filter/reduce package (plus some goodies) mostly inspired by Rob Pike's filter package, but this time with generics and simpler implementations.

That said, you should probably still stick to loops.

Installation#

% go get -u tangled.org/luka.ljudi.org/reduce

Note: When you copy the command, make sure not to include the % prefix.

Usage#

This is the entire API:

func All[S ~[]T, T any](s S, f func(T) bool) bool
func Any[S ~[]T, T any](s S, f func(T) bool) bool

func Not[T any](f func(T) bool) func(T) bool

func Filter[S ~[]T, T any](s S, f func(T) bool) S
func FilterInPlace[S ~[]T, T any](s S, f func(T) bool) S

func Map[S ~[]T, T any, U any](s S, f func(T) U) []U
func MapInPlace[S ~[]T, T any](s S, f func(T) T) S

func Reduce[S ~[]T, T any, U any](s S, acc U, f func(U, T) U) U
