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

Now returns a valid NullTime with the time set to now, in UTC and rounded to the nearest millisecond. It does this so that JSON- and SQL-serialization and deserialization yields the same time as passed in. If the time is not UTC or has sub-millisecond accuracy, the time retrieved from an SQL DB or JSON object might not be equal to the original object due to rounding and automatic timezone conversion.

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)
