Functions

func TypesMap

func TypesMap() map[uint32]string

TypesMap returns mapping from type ids to TL type names.

Types

type GZIP

type GZIP struct {
	Data []byte
}

GZIP represents a Packed Object.

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

func (*GZIP) Decode

func (g *GZIP) Decode(b *bin.Buffer) error

Decode implements bin.Decoder.

func (GZIP) Encode

func (g GZIP) Encode(b *bin.Buffer) error

Encode implements bin.Encoder.

type GetConfig

type GetConfig struct{}

GetConfig is help.getConfig#c4f9186b function.

func (GetConfig) Decode

func (GetConfig) Decode(b *bin.Buffer) error

Decode implements bin.Decoder.

func (GetConfig) Encode

func (GetConfig) Encode(b *bin.Buffer) error

Encode implements bin.Encoder.

type InitConnection

type InitConnection struct {
	Flags          bin.Fields
	ID             int
	DeviceModel    string
	SystemVersion  string
	AppVersion     string
	SystemLangCode string
	LangPack       string
	LangCode       string

	Query TType
}

InitConnection is initConnection#c1cd5ea9 function.

func (InitConnection) Decode

func (i InitConnection) Decode(b *bin.Buffer) (err error)

Decode implements bin.Decoder.

func (InitConnection) Encode

func (i InitConnection) Encode(b *bin.Buffer) error

Encode implements bin.Encoder.

type InvokeWithLayer

type InvokeWithLayer struct {
	Layer int
	Query TType
}

InvokeWithLayer is invokeWithLayer#da9b0d0d function.

invokeWithLayer#da9b0d0d {X:Type} layer:int query:!X = X;

https://core.telegram.org/method/invokeWithLayer

func (InvokeWithLayer) Decode

func (i InvokeWithLayer) Decode(b *bin.Buffer) (err error)

Decode implements bin.Decoder.

func (InvokeWithLayer) Encode

func (i InvokeWithLayer) Encode(b *bin.Buffer) error

Encode implements bin.Encoder.

type Message

type Message struct {
	ID    int64
	SeqNo int
	Bytes int
	Body  []byte
}

Message is element of MessageContainer.

func (*Message) Decode

func (m *Message) Decode(b *bin.Buffer) error

Decode implements bin.Decoder.

type MessageContainer

type MessageContainer struct {
	Messages []Message
}

MessageContainer contains slice of messages.

func (*MessageContainer) Decode

func (m *MessageContainer) Decode(b *bin.Buffer) error

Decode implements bin.Decoder.

type MessageID

type MessageID int64

MessageID represents 64-bit message id.

func NewMessageID

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

NewMessageID returns new message id for provided time and type.

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 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
)

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

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

Encode implements bin.Encoder.

type TType

type TType interface {
	bin.Encoder
	bin.Decoder
}

TType represents any generic T in TL Schema.

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.
