The Broadcast Manager protocol provides a command based configuration interface to filter and send (e.g. cyclic) CAN messages in kernel space. Filtering messages in kernel space may significantly reduce the load in an application.
A BCM socket is not intended for sending individual CAN frames. To send invidiual frames use the tokio-socketcan crate.
This crate would not have been possible without the socketcan crate.
```Rust use std::time; use tokiosocketcanbcm::*; use futures_util::stream::StreamExt;
async fn main() { let socket = BCMSocket::opennb("vcan0").unwrap(); let ival = time::Duration::frommillis(0);
// create a stream of messages that filters by the can frame id 0x123
let mut can_frame_stream = socket
.filter_id_incoming_frames(0x123.into(), ival, ival)
.unwrap();
while let Some(frame) = can_frame_stream.next().await {
println!("Frame {:?}", frame);
()
}
} ```
