Functions

func Last

func Last[T any](s []T, f func(T) bool) (*T, int, bool)

Returns the last element in the slice where the predicate returns true

func Map

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

Map maps elements of a slice from T to M, returning a new slice.

func MapWithErr

func MapWithErr[T any, S any](s []T, f func(T) (S, error)) ([]S, error)

MapWithErr maps elements of a slice from T to M, returning a new slice and a joined error if there are any. If an error is returned from the mapping function, a nil array and the error is returned.

func UniqueGroupBy

func UniqueGroupBy[T any, U comparable, Slice ~[]T](collection Slice, iteratee func(item T) U) (map[U]T, bool)
