Migration to futures-rs/tokio about capnproto-rust HOT 7 CLOSED

I agree that we should migrate to futures-rs and tokio-core. I've made some progress in that direction with the capnp-futures-rs crate, but there is still a lot to do. Please keep me posted on any progress you make, and feel free to ask me any questions.

This is done! See https://dwrensha.github.io/capnproto-rust/2017/01/04/rpc-futures.html.

@salpalvv: I've added some more documentation to the readme at https://github.com/dwrensha/capnp-rpc-rust. Perhaps we should also have fully-working "hello" example in the /examples/ directory.

Well, i'm studying the code, and the rpc protocol specification, read the code of the new and old create, and i'm lost yet. And I have one question:

1. How you visualize the migration, ¿what's the next file you could migrate?, because i don't know where to start really

Well, the light is coming to me. My attemp is starting here: https://github.com/gabomgp/capnp-rpc-tokio. There is ver little yet, but i hope i can help.

I would start by updating this declaration in the capnp crate to be

pub type Promise<T,E> = Box<::futures::Future<Item=T,Error=E>>;

I would then update the capnpc crate so that code generation still produces code that typechecks. Then I would start on capnp-rpc.

I've started working on this: https://github.com/dwrensha/capnproto-rust/tree/futures, https://github.com/dwrensha/capnpc-rust/tree/futures, https://github.com/dwrensha/capnp-rpc-rust/tree/futures

While I eagerly await the futures implementation, I went ahead and dove into capnproto-rust with the gj dep because I plan to use capnproto-rpc for my project.

One issue that I had was the lack of very simple examples. I had to go to this blog post to find a simple hello world example.

I would like to suggest that when you have the futures implementation that you have an extremely simple, contrived example (hello world is always great) so even I may follow along. Futures are very complex as is and I imagine having to follow along with a pubsub and calculator examples may prove difficult.
