Crate can_socket

CAN socket

This library exposes a CanSocket and related types, allowing you to communicate over a Controller Area Network (CAN) bus.

The is a standard blocking or non-blocking CanSocket, and an asynchronous tokio::CanSocket.

This library uses the SocketCAN interface and only works on Linux.

Supported features:

• Bind sockets to specific interfaces by name or index.
• Bind sockets to all CAN interfaces at the same time.
• Send and receive data frames and RTR frames.
• Send and receive standard frames and extended frames.
• Setting per-socket filters.
• Control over the loopback and recv_own_msgs options.
• Constructing compile-time checked CAN IDs.

Modules

• error
  Error types.
• tokiotokio
  Support for tokio.

Macros

• can_id
  Construct an CanId (standard or extended) that is checked at compile time.
• extended_id
  Construct an ExtendedId that is checked at compile time.
• standard_id
  Construct a StandardId that is checked at compile time.

Structs

• CanData
  The data payload of a CAN frame.
• CanFilter
  A CAN filter.
• CanFrame
  A CAN frame as transmitted over a CAN socket.
• CanInterface
  A CAN interface identified by its index.
• CanSocket
  A synchronous CAN socket.
• ExtendedId
  An extended 29 bit CAN ID.
• StandardId
  A standard 11 bit CAN ID.

Enums

• CanId
  A CAN ID, either standard (11 bit) or extended (29 bits).

Constants

• MAX_EXTENDED_ID
  The highest valid value for an extended CAN ID.
• MAX_STANDARD_ID
  The highest valid value for a standard CAN ID.

Traits

• Deadline
  Trait for types that can be used as a timeout or deadline.
