func Of

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

Of returns a pointer that points to equivalent value of value v. (T → *T). It is useful when you want to "convert" a unaddressable value to pointer.

If you need to assign the address of a literal to a pointer:

 payload := struct {
	    Name *string
 }

The practice without generic:

x := "name"
payload.Name = &x

Use generic:

payload.Name = Of("name")

💡 HINT: use [Indirect] to dereference pointer (*T → T).

⚠️ WARNING: The returned pointer does not point to the original value because Go is always pass by value, user CAN NOT modify the value by modifying the pointer.
