Functions

func CloseIgnore

func CloseIgnore(c io.Closer)

CloseIgnore closes c, ignoring any error. Its main use is to satisfy linters.

func Filter

func Filter[Elem any](src []Elem, fn func(Elem) bool) []Elem

Filter applies fn on all elements in src, producing a new slice containing the elements for which fn returned true, preserving the same order.

func Map

func Map[A, B any](src []A, fn func(A) B) []B

Map applies fn on all elements in src, producing a new slice with the results, in order.

func MapKeys

func MapKeys[M ~map[K]V, K comparable, V any](m M) []K

MapKeys returns the keys of the map m. The keys will be in an indeterminate order.
