Types

type ProtoWrapperCodec

type ProtoWrapperCodec struct {
	FieldIndex int
}

Codec for encoding gRPC wrappers.BoolValue, which exposes an API for having nullable boolean values.

func MustWrapperCodec

func MustWrapperCodec(protoMessage proto.Message) ProtoWrapperCodec

func NewWrapperCodec

func NewWrapperCodec(protoMessage interface{}) (ProtoWrapperCodec, error)

Builds the wrapper codec for a given proto message.

Wrapper messages must:

• Have exactly 1 non-embedded public field. This field's value will be extracted and marshalled as the bson value.

func (ProtoWrapperCodec) DecodeValue

func (codec ProtoWrapperCodec) DecodeValue(
	context bsoncodec.DecodeContext, reader bsonrw.ValueReader, value reflect.Value,
) error

func (ProtoWrapperCodec) EncodeValue

func (codec ProtoWrapperCodec) EncodeValue(
	context bsoncodec.EncodeContext, writer bsonrw.ValueWriter, value reflect.Value,
) error
