Module tor_cell::chancell

Messages sent over Tor channels

A ‘channel’ is a direct connection between a tor client and a relay, or between two relays. Current channels all use TLS.

This module implements the ChanCell type, which is the encoding for data sent over a channel. It also encodes and decodes various channel messages, which are the types of data conveyed over a channel.

Modules

• codec
  Implementation for encoding and decoding of ChanCells.
• msg
  Different kinds of messages that can be encoded in channel cells.

Structs

• ChanCell
  A decoded channel cell, to be sent or received on a channel.
• ChanCmd
  A ChanCmd is the type of a channel cell. The value of the ChanCmd indicates the meaning of the cell, and (possibly) its length.
• CircId
  Channel-local identifier for a circuit.

Constants

• CELL_DATA_LEN
  The amount of data sent in a fixed-length cell.

Traits

• ChanMsg
  Trait implemented by anything that can serve as a channel message.

Type Aliases

• AnyChanCell
  A decoded and parsed channel cell of unrestricted type.
• BoxedCellBody
  A RawCellBody stored on the heap.
• RawCellBody
  A cell body considered as a raw array of bytes
