Functions

func Filter

func Filter[T any](arr []T, fn func(in T, index int) bool) []T

func Find

func Find[T any](arr []T, predict func(T) bool) T

Find returns the first element in the slice that satisfies the provided testing function. Otherwise zero value is returned.

func FindIndex

func FindIndex[T any](arr []T, predict func(T) bool) int

FindIndex returns the index of the first element in the slice that satisfies the provided testing function. Otherwise -1 is returned.

func FindP

func FindP[T any](arr []T, predict func(*T) bool) *T

FindP returns the first element in the slice that satisfies the provided testing function. Otherwise nil is returned.

func Flat

func Flat[T any](arr [][]T) []T

func Flats

func Flats[T any](arr ...[]T) []T

func Map

func Map[I, O any](arr []I, fn func(in I, index int) O) []O

func MapE

func MapE[I, O any](arr []I, fn func(in I, index int) (O, error)) ([]O, error)

func Reduce

func Reduce[I, O any](arr []I, fn func(acc O, in I, index int) O, acc O) O

func ReduceE

func ReduceE[I, O any](arr []I, fn func(acc O, in I, index int) (O, error), acc O) (O, error)

func Zip

func Zip[T any](args ...[]T) [][]T

Zip joins multiple slices

For example, Zip([a, b, c], [d, e, f]) returns [[a, d], [b, e], [c, f]] Each slice must have the same length (or it's an UB or even panic)

func ZipFlat

func ZipFlat[T any](args ...[]T) []T

ZipFlat likes Zip, but returns a flat slice
