Crate warp_json_rpc

Usage

use warp_json_rpc::{filters as json_rpc, Builder};
use futures::future;
use warp::Filter as _;
use std::convert::Infallible;

#[tokio::main]
async fn main() {
  // create Filter
  let route = warp::filters::path::path("rpc")
    // ## Point 1
    // This filter is required.
    .and(json_rpc::json_rpc())
    .and(json_rpc::method("add"))
    .and(json_rpc::params::<(usize, usize)>())
    // `res.success` returns `impl Reply` which represents JSON RPC Response
    .map(|res: Builder, (lhs, rhs)| res.success(lhs + rhs).unwrap());

  // ## Point 2
  // You **MUST** wraps root `Filter` by `warp_json_rpc::service` function.
  let svc = warp_json_rpc::service(route);
  let make_svc = hyper::service::make_service_fn(move |_| {
    future::ok::<_, Infallible>(svc.clone())
  });
  hyper::Server::bind(&([127, 0, 0, 1], 3030).into())
    .serve(make_svc)
    .await
    .unwrap();
}
