Crate rbfrt

This crate implements an interface to a P4-programmable switch that can be controlled through the BFRuntime Interface.

Example

use rbfrt::{SwitchConnection, table};
use rbfrt::table::{MatchValue, Request};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let switch = SwitchConnection::builder("localhost", 50052)
        .device_id(0)
        .client_id(1)
        .p4_name("my_p4_program")
        .connect()
        .await?;


    let requests = vec![
        Request::new("ingress.p4tg.frame_type.frame_type_monitor")
            .match_key("hdr.ipv4.dst_addr", MatchValue::lpm(vec![10u8, 0, 0, 2], 32))
            .match_key("ig_intr_md.ingress_port", MatchValue::exact(0)),
        Request::new("ingress.p4tg.tg_forward")
            .match_key("ig_intr_md.ingress_port", MatchValue::exact(10))
            .match_key("ig_md.rand_value", MatchValue::range(20, 30))
            .match_key("hdr.pkt_gen.app_id", MatchValue::exact(5))
        ];

    for req in requests {
        let entries = switch.get_table_entries(req).await?;

        for e in entries {
            println!("{:?}", e);
        }
    }

    Ok(())
}
