Types

type Codec 

type Codec interface {
	MarshalInto(interface{}, *wrappers.Packer) error
	Unmarshal([]byte, interface{}) error

	// Returns the size, in bytes, of [value] when it's marshaled
	Size(value interface{}) (int, error)
}

Codec marshals and unmarshals

type Foo 

type Foo interface {
	Foo() int
}

type GeneralCodec 

type GeneralCodec interface {
	Codec
	Registry
}

GeneralCodec marshals and unmarshals structs including interfaces

type Manager 

type Manager interface {
	// Associate the given codec with the given version ID
	RegisterCodec(version uint16, codec Codec) error

	// Size returns the size, in bytes, of [value] when it's marshaled
	// using the codec with the given version.
	// RegisterCodec must have been called with that version.
	// If [value] is nil, returns [ErrMarshalNil]
	Size(version uint16, value interface{}) (int, error)

	// Marshal the given value using the codec with the given version.
	// RegisterCodec must have been called with that version.
	Marshal(version uint16, source interface{}) (destination []byte, err error)

	// Unmarshal the given bytes into the given destination. [destination] must
	// be a pointer or an interface. Returns the version of the codec that
	// produces the given bytes.
	Unmarshal(source []byte, destination interface{}) (version uint16, err error)
}

Manager describes the functionality for managing codec versions.

func (m *MockManager) RegisterCodec(arg0 uint16, arg1 Codec) error

RegisterCodec mocks base method.

func (*MockManager) Size 

func (m *MockManager) Size(arg0 uint16, arg1 any) (int, error)

Size mocks base method.

func (*MockManager) Unmarshal 

func (m *MockManager) Unmarshal(arg0 []byte, arg1 any) (uint16, error)

Unmarshal mocks base method.

type MockManagerMockRecorder 

type MockManagerMockRecorder struct {

}

MockManagerMockRecorder is the mock recorder for MockManager.

func (*MockManagerMockRecorder) Marshal 

func (mr *MockManagerMockRecorder) Marshal(arg0, arg1 any) *gomock.Call

Marshal indicates an expected call of Marshal.

func (*MockManagerMockRecorder) RegisterCodec 

func (mr *MockManagerMockRecorder) RegisterCodec(arg0, arg1 any) *gomock.Call

RegisterCodec indicates an expected call of RegisterCodec.

func (*MockManagerMockRecorder) Size 

func (mr *MockManagerMockRecorder) Size(arg0, arg1 any) *gomock.Call

Size indicates an expected call of Size.

func (*MockManagerMockRecorder) Unmarshal 

func (mr *MockManagerMockRecorder) Unmarshal(arg0, arg1 any) *gomock.Call

Unmarshal indicates an expected call of Unmarshal.

type MultipleVersionsStruct 

type MultipleVersionsStruct struct {
	BothTags    string `tag1:"true"  tag2:"true"`
	SingleTag1  string `tag1:"true"`
	SingleTag2  string `             tag2:"true"`
	EitherTags1 string `tag1:"false" tag2:"true"`
	EitherTags2 string `tag1:"true"  tag2:"false"`
	NoTags      string `tag1:"false" tag2:"false"`
}

type MyInnerStruct 

type MyInnerStruct struct {
	Str string `serialize:"true"`
}

func (*MyInnerStruct) Foo 

func (*MyInnerStruct) Foo() int

type MyInnerStruct2

	M1  MyInnerStruct `serialize:"true"`
	F   Foo           `serialize:"true"`
}

MyInnerStruct3 embeds Foo, an interface, so it has to implement TypeID and ConcreteInstance

type Registry 

type Registry interface {
	RegisterType(interface{}) error
}

Registry registers new types that can be marshaled into
