func AsFilterIteratee ¶

func AsFilterIteratee[T any](f func(T) bool) func(T, int) bool

func EmptyAsNil ¶

func EmptyAsNil[T any](s []T) []T

EmptyAsNil returns nil if the slice is empty otherwise the slice is returned. This is useful when in tests we are checking struct equality, as we don't need to care about the slice being zero length or nil.

func ForEachUntilWithErr ¶

func ForEachUntilWithErr[T any](s []T, f func(T, int) (breaks bool, err error)) error

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 SliceToPtrSlice ¶

func SliceToPtrSlice[T any](s []T) []*T

func UniqueGroupBy ¶

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