Functions

func Of

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

Of returns pointer of a given generic type

Example:

var v int
var p = ptr.Of(v)

func Safe

func Safe[T any](v *T) T

Safe dereferences safely a pointer - if the pointer is nil => returns the zero value of the type of the pointer if nil - if the pointer is not nil => returns the dereferenced pointer

Example:

var v *int
var x = ptr.Safe(v)

func When

func When[T any](v T, condition bool) *T

When returns pointer of a given generic type - if the condition is false => returns nil - if the condition is true => returns pointer of the value

Example:

var v bool
var p = ptr.When(v, v != false)
