Functions

func Map

func Map[V any, R any](slice []V, mapper func(entry V) R) []R

Map applies the mapper function to each entry in the slice and returns a new slice with the results.

func MapFilter

func MapFilter[V any, R comparable](slice []V, mapper func(entry V) R) []R

MapFilter applies the mapper function to each entry in the slice and returns a new slice with the results.

If mapper returns the default value for the R type, the result is not added to the returned slice.

func ToString

func ToString[T stringer](v T) string

ToString is a function useful to pass into a mapper, to map all values to a string.
