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

	// Define the maximum size, in bytes, of something serialized/deserialized
	// by this codec manager
	SetMaxSize(int)

	// 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 NewDefaultManager 

func NewDefaultManager() Manager

NewDefaultManager returns a new codec manager.

func NewManager 

func NewManager(maxSize int) Manager

NewManager returns a new codec manager.

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 

type MyInnerStruct2 struct {
	Bool bool `serialize:"true"`
}

func (*MyInnerStruct2) Foo 

func (*MyInnerStruct2) Foo() int

type MyInnerStruct3 

type MyInnerStruct3 struct {
	Str string        `serialize:"true"`
	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
