Crate can_hal_socketcan 

can-hal-socketcan

Linux SocketCAN backend for can_hal traits.

This crate provides SocketCanDriver and SocketCanChannel which implement the hardware-agnostic CAN traits defined in can-hal, enabling portable CAN application code to run on Linux systems with SocketCAN interfaces.

Example

use can_hal::{CanId, CanFrame, Transmit, Receive, ChannelBuilder};
use can_hal_socketcan::SocketCanDriver;

let driver = SocketCanDriver::new();
let mut channel = driver
    .channel_by_name("vcan0")
    .unwrap()
    .bitrate(500_000)
    .unwrap()
    .connect()
    .unwrap();

let id = CanId::new_standard(0x123).unwrap();
let frame = CanFrame::new(id, &[0xDE, 0xAD]).unwrap();
channel.transmit(&frame).unwrap();

Bitrate Configuration

SocketCAN bitrate is configured at the OS level, not through the socket API. Use ip link set or netlink before opening a channel:

sudo ip link set can0 type can bitrate 500000
sudo ip link set can0 up

The builder’s bitrate() / data_bitrate() / sample_point() methods store values for informational purposes but do not apply them.
