Used to replace any other object (or rather, a serialization thereof) with its archived (gzipped) representation.

Decode implements bin.Decoder.

type MessageContainer 

type MessageContainer struct {
	Messages []Message
}

MessageContainer contains slice of messages.

func (*MessageContainer) Decode

type MessageID 

type MessageID int64

MessageID represents 64-bit message id.

func NewMessageID(now time.Time, typ MessageType) MessageID

NewMessageID returns new message id for provided time and type.

func (MessageID) String added in v0.19.0 

func (id MessageID) String() string

func (MessageID) Time 

func (id MessageID) Time() time.Time

Time returns approximate time when MessageID were generated.

func (MessageID) Type 

func (id MessageID) Type() MessageType

Type returns message type.

type MessageIDBuf added in v0.25.0 

type MessageIDBuf struct {
	// contains filtered or unexported fields
}

MessageIDBuf stores last N message ids and is used in replay attack mitigation.

func NewMessageIDBuf added in v0.25.0 

func NewMessageIDBuf(n int) *MessageIDBuf

NewMessageIDBuf initializes new message id buffer for last N stored values.

func (*MessageIDBuf) Consume added in v0.25.0 

func (b *MessageIDBuf) Consume(newID int64) bool

Consume returns false if message should be discarded.

type MessageIDGen added in v0.16.0 

type MessageIDGen struct {
	// contains filtered or unexported fields
}

MessageIDGen is message id generator that provides collision prevention.

The main reason of such structure is that now() can return same time during multiple calls and that leads to duplicate message id.

func NewMessageIDGen added in v0.16.0 

func NewMessageIDGen(now func() time.Time, n int) *MessageIDGen

NewMessageIDGen creates new message id generator.

Current time will be provided by now() function. The n parameter configures capacity of message id history, bigger n results in bigger memory consumption.

func (*MessageIDGen) New added in v0.16.0 

func (g *MessageIDGen) New(t MessageType) int64

New generates new message id for provided type, protecting from collisions that are caused by low system time resolution.

type MessageType 

type MessageType byte

MessageType is type of message determined by message id.

A message is rejected over 300 seconds after it is created or 30 seconds before it is created (this is needed to protect from replay attacks).

The identifier of a message container must be strictly greater than those of its nested messages. 

const (
	// MessageUnknown reports that message id has unknown time and probably
	// should be ignored.
	MessageUnknown MessageType = iota
	// MessageFromClient is client message identifiers.
	MessageFromClient
	// MessageServerResponse is a response to a client message.
	MessageServerResponse
	// MessageFromServer is a message from the server.
	MessageFromServer
)

func (MessageType) String added in v0.19.0 

func (m MessageType) String() string

type Result 

type Result struct {
	RequestMessageID int64
	Result           []byte
}

Result is rpc_result#f35c6d01.

func (*Result) Decode 

func (r *Result) Decode(b *bin.Buffer) error

Decode implements bin.Decoder.

func (*Result) Encode added in v0.11.0 

func (r *Result) Encode(b *bin.Buffer) error

Encode implements bin.Encoder.

type UnencryptedMessage 

type UnencryptedMessage struct {
	MessageID   int64
	MessageData []byte
}

UnencryptedMessage is plaintext message.

func (*UnencryptedMessage) Decode 

func (u *UnencryptedMessage) Decode(b *bin.Buffer) error

Decode implements bin.Decoder.

func (UnencryptedMessage) Encode 

func (u UnencryptedMessage) Encode(b *bin.Buffer) error

Encode implements bin.Encoder.
