func Contains ¶

func Contains[T comparable](slice []T, value T) bool

func Filter ¶

func Filter[T any](slice []T, fn func(T) bool) []T

func FilterVariants ¶

func FilterVariants[T any, U any](slice []U) iter.Seq[T]

FilterVariants finds all elements in a slice that can be cast to the given type.

func Find ¶

func Find[T any](slice []T, fn func(T) bool) (T, bool)

func FindVariant ¶

func FindVariant[T any, U any](slice []U) (T, bool)

FindVariant finds the first element in a slice that can be cast to the given type.

func FlatMap ¶

func FlatMap[T, U any](slice []T, fn func(T) []U) []U

func GroupBy ¶

func GroupBy[T any, K comparable](slice []T, fn func(T) K) map[K][]T

GroupBy groups the elements of a slice by the result of a function.

func Map ¶

func Map[T, U any](slice []T, fn func(T) U) []U

func MapErr ¶

func MapErr[T, U any](slice []T, fn func(T) (U, error)) ([]U, error)

func Reduce ¶

func Reduce[T, U any](slice []T, initial U, fn func(U, T) U) U

func RemoveAll ¶ added in v0.482.1

func RemoveAll[T comparable](slice []T, values []T) []T

RemoveAll removes all elements in a slice that are in another slice.

func Reverse ¶

func Reverse[T any](slice []T)

Reverse reverses a slice of any type in place.

func Sort ¶

func Sort[T cmp.Ordered](slice []T) []T

Sort returns a sorted clone of slice.

func Unique ¶

func Unique[T comparable](slice []T) []T

Unique returns a new slice containing only the unique elements of the input, with the order preserved.
