 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](https://crates.io/crates/tokio-socketcan) crate.



This crate would not have been possible without the [socketcan crate](https://github.com/mbr/socketcan-rs).



# Example



```Rust

use std::time;

use futures_util::stream::StreamExt;

use tokio_socketcan_bcm::{BCMSocket, Id, StandardId};



#[tokio::main]

async fn main() {

    let socket = BCMSocket::open_nb("vcan0").unwrap();

    let ival = time::Duration::from_millis(0);



    // create a stream of messages that filters by the can frame id 0x123

    let id = Id::Standard(StandardId::new(0x123).unwrap());

    let mut can_frame_stream = socket

        .filter(id, ival, ival)

        .unwrap();



    while let Some(frame) = can_frame_stream.next().await {

        println!("Frame {:?}", frame);

        ()

    }

}

```
