Types

type NullInt

type NullInt struct {
	Int   int
	Valid bool // Valid is true if Int is not NULL
}

NullInt represents an int that may be null. NullInt implements the Scanner interface so it can be used as a scan destination, similar to NullString.

func (NullInt) MarshalJSON

func (i NullInt) MarshalJSON() ([]byte, error)

MarshalJSON implements the encoding/json.Marshaler interface.

func (*NullInt) Scan

func (n *NullInt) Scan(value interface{}) error

Scan implements the Scanner interface.

func (*NullInt) UnmarshalJSON

func (i *NullInt) UnmarshalJSON(data []byte) error

UnmarshalJSON implements the encoding/json.Unmarshaler interface.

func (NullInt) Value

func (n NullInt) Value() (driver.Value, error)

Value implements the driver Valuer interface.

type NullTime

type NullTime struct {
	Time  time.Time
	Valid bool // Valid is true if Time is not NULL
}

func Now

func Now() NullTime

func (NullTime) MarshalJSON

func (nt NullTime) MarshalJSON() ([]byte, error)

MarshalJSON implements the json.Marshaler interface.

func (*NullTime) Scan

func (nt *NullTime) Scan(value interface{}) error

Scan implements the Scanner interface.

func (NullTime) String

func (nt NullTime) String() string

func (*NullTime) UnmarshalJSON

func (nt *NullTime) UnmarshalJSON(data []byte) (err error)

UnmarshalJSON implements the json.Unmarshaler interface.

func (NullTime) Value

func (nt NullTime) Value() (driver.Value, error)

Value implements the driver Valuer interface.

type StringSlice

type StringSlice struct {
	Slice []string
}

func NewSlice

func NewSlice(goslice []string) *StringSlice

func (*StringSlice) Scan

func (s *StringSlice) Scan(v interface{}) error

func (*StringSlice) Value

func (s *StringSlice) Value() (driver.Value, error)
