Functions

func Filter

func Filter[E any](elements []E, test func(e E) bool) []E

Filter returns a subset of elements for each test which is true

func Identity

func Identity[V any](input V) V

Identity is an f(x) = x function. Really useful for testing.

func Map

func Map[I any, O any](inputs []I, transform func(i I) O) []O

Map transforms a slice of inputs through the transform function to result in an equal sized slice of outputs.

func Split

func Split[E any](elements []E, test func(e E) bool) ([]E, []E)

Split applies all elements e to test. All e which test returns true are in the first slice, all others are in the second slice. Useful for splitting a slice into two buckets to be further operated on. Filter discards the negative results of test which is more efficient if no further processing needs to occur.
