Functions

func BoolSize

func BoolSize(b bool) uint32

func GCD_U16

func GCD_U16(a, b uint16) uint16

func MarshalBool

func MarshalBool(v bool) (buf []byte)

func MarshalString

func MarshalString(str string) (buf []byte)

func MillisToUTCTime

func MillisToUTCTime(millis uint64) time.Time

func NullableSize

func NullableSize(o dmeta.Field) uint32

func OptionalBoolSize

func OptionalBoolSize(b *bool) uint32

func OptionalSize

func OptionalSize(o dmeta.Field) uint32

func OptionalStringSize

func OptionalStringSize(s *string) uint32

OptionalStringSize returns either 0 if the given value is nil, or len(*value) + 2 (for quotes).

func OptionalTimeSize

func OptionalTimeSize(t *time.Time) uint32

func StringSize

func StringSize(s string) uint32

StringSize returns len(string) + 2.

func TriStateStringSize

func TriStateStringSize(s *string, null bool) uint32

TriStateStringSize returns the size in bytes of the given value for the three possible states: absent, null, populated.

If the given value is nil and null is false, returns 0 (absent).

If the given value is nil and null is true, returns 4 (len("null")).

If the given value is non-nil, len(*value) + 2 (for quotes) is returned.

func UnmarshalString

func UnmarshalString(val []byte) (string, error)

deprecated

func UnmarshalStringInto

func UnmarshalStringInto(val []byte, to *string) error
