Bring JSON RPC features into warp world.

Filters

• json_rpc
  • requires the request to follow basic JSON RPC specification.
  • YOU HAVE TO CALL THIS FILTER BEFORE ANY OF BELOW FILTERS.
• method
  • requires the request RPC method to be given name.
• params
  • extracts RPC parameter.

Example

```rust use warpjsonrpc::filters as json_rpc; use futures::future; use warp::Filter as _;

[tokio::main]

async fn main() { // create Filter let route = warp::filters::path::path("rpc") // ## Point 1 // This filter is required. .and(jsonrpc::jsonrpc()) .and(jsonrpc::method("add")) .and(jsonrpc::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 = warpjsonrpc::service(route); let makesvc = hyper::service::makeservicefn(move || future::ok::<_, Infallible>(svc));

hyper::Server::bind(&([127, 0, 0, 1], 3030).into()) .serve(make_svc) .await .unwrap(); } ```
