Types

type Nullable

type Nullable[T any] struct {
	Data  T
	Valid bool
}

Nullable represents data that also can be NULL

func Null

func Null[T any]() Nullable[T]

Null Create a Nullable that is NULL with type

func Value

func Value[T any](value T) Nullable[T]

Value Create a Nullable from a value

func ValueFromPointer

func ValueFromPointer[T any](value *T) Nullable[T]

ValueFromPointer Create a Nullable from a pointer

func (Nullable[T]) Equal

func (n Nullable[T]) Equal(other Nullable[T]) bool

Equal Check if this Nullable is equal to another Nullable

func (Nullable[T]) ExactEqual

func (n Nullable[T]) ExactEqual(other Nullable[T]) bool

ExactEqual Check if this Nullable is exact equal to another Nullable, never using intern Equal method to check equality
