Module grammers_mtproto::mtp

Implementation of the Mobile Transport Protocol. This layer is responsible for converting zero or more input requests into outgoing messages, and to process the response.

A distinction between plain and encrypted is made for simplicity (the plain hardly requires to process any state) and to help prevent invalid states (encrypted communication cannot be made without an authorization key).

Structs

• Deserialization
  Results from the deserialization of a response.
• Encrypted
  An implementation of the Mobile Transport Protocol for ciphertext (encrypted) messages.
• Plain
  An implementation of the Mobile Transport Protocol for plaintext (unencrypted) messages.
• RpcError
  The error type reported by the server when a request is misused.

Enums

• DeserializeError
  The error type for the deserialization of server messages.
• RequestError
  This error occurs when a Remote Procedure call was unsuccessful.

Constants

• ENCRYPTED_PACKET_HEADER_LEN
  Data prepended after encrypting a packet, key_id and msg_key.
• MAX_TRANSPORT_HEADER_LEN
  The maximum header length used by any available transport (Full, 4 bytes for len and seq).
• MESSAGE_CONTAINER_HEADER_LEN
  The message header for the container occupies the size of the message header (msg_id, seq_no and size) followed by the container header (constructor, len).
• PLAIN_PACKET_HEADER_LEN
  The first actual message comes after salt, client_id (8 bytes each).

Traits

• Mtp
  The trait used by the Mobile Transport Protocol to serialize outgoing messages and deserialize incoming ones into proper responses.
