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.
