### Transport agnostic jsonrpc library. Right now it supports only server side handling requests. ```rust use jsonrpc_core::IoHandler; use jsonrpc_core::Value; let mut io = IoHandler::new(); io.add_sync_method("say_hello", |_| { Ok(Value::String("Hello World!".into())) }); let request = r#"{"jsonrpc": "2.0", "method": "say_hello", "params": [42, 23], "id": 1}"#; let response = r#"{"jsonrpc":"2.0","result":"Hello World!","id":1}"#; assert_eq!(io.handle_request_sync(request), Some(response.to_string())); ```
