Functions

func Filter

func Filter[T any](tPtr *T, p funcs.Predicate[T]) *T

func FilterNot

func FilterNot[T any](t *T, p funcs.Predicate[T]) *T

func Map

func Map[T any, R any](t *T, mapper funcs.Mapper[T, R]) *R

func Nil

func Nil[T any]() *T

func None

func None[T any]() *T

func Of

func Of[T any](t T) *T

Of is useful when one needs a one-liner for pointer of expression result; one needs to understand, the t will be passed as a copy, and `ptr.Of(x)` will result in pointer to copy of x.
