p4 controller in Rust

Work in Progress

I hope I can finish this.

Rusty P4

A Work-in-progress composable and lightweight library for writing P4Runtime controller in Rust. The goal is to bring powerful & expressive tools into the world of P4 and SDN so that developers can test their ideas faster.

It's trying to provide multi-level APIs for writing controllers with different complexity (see Examples below). Some design come from the tutorials of P4 and ONOS.

Repo structure

• rusty-p4-core. The core of rusty-p4, providing the basic building blocks like App trait, Service trait, P4 runtime, Pipeconf, flow and some other things.
• rusty-p4-packet. Provides methods to parse packets.
• rusty-p4-northbound. Provides impls for northbound server.
• rusty-p4-app. Provides some simple application implementation.

Getting Started

Current version hasn't been published, so to use it, add

rusty-p4 = { git="https://github.com/another-s347/rusty-p4" }

to your Cargo.toml.

Built With

• tonic - gRPC for Rust.
• PI - P4Runtime
• tokio - The asynchronous run-time for the Rust programming language.

rusty-p4's Issues

I like these code because

I did not learned RUST

cheer up! God K

could not get this to build

This looks like a useful project, I would very much like to play with it!

With nightly rust (which is required) and the master branch, I get a lot of errors of this form while building:

error[E0277]: the trait bound `proto::v1::WriteRequest: prost::message::Message` is not satisfied
   --> /home/bpfaff/dddp/rusty-p4/target/debug/build/rusty-p4-proto-13932b727387435a/out/p4.v1.rs:953:199

    |                   ------- required by this bound in `grpcio::ser`

I played with it for some time and could not figure it out. I am a relative novice in Rust.

On the dev branch, with nightly rust, rusty-p4 builds OK, but so far I haven't been able to massage the first example from the Readme into working (although I'm still working on it). There isn't, for example, anything in the tree called P4InfoHelper, which the example tries to use. I could also not find where ParamValue::of is supposed to come from. And the example/ crate fails to build with errors that start out like this:

error: expected `:`
  --> src/bin/example.rs:30:17
   |
30 |             pipe="IngressPipeImpl";
   |                 ^
   |
   = note: this error originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info)

error: expected `:`

bootstrap.sh missing

Readme.md says:

2. Run bootstrap.sh.  

The repo doesn't contain such a file, or anything with a similar name.
