//! A fast and lightweight async implementation of [JSON-RPC
//! 2.0](https://www.jsonrpc.org/specification), supporting the Tcp and Unix protocols.
//!
//! # Example
//!
//! ```
//! use std::sync::Arc;
//!
//! use serde_json::Value;
//! use smol::net::{TcpStream, TcpListener};
//!
//! use karyon_jsonrpc::{JsonRPCError, Server, Client, register_service, ServerConfig, ClientConfig};
//!
//! struct HelloWorld {}
//!
//! impl HelloWorld {
//!     async fn say_hello(&self, params: Value) -> Result<Value, JsonRPCError> {
//!         let msg: String = serde_json::from_value(params)?;
//!         Ok(serde_json::json!(format!("Hello {msg}!")))
//!     }
//! }
//!
//! // Server
//! async {
//!     let ex = Arc::new(smol::Executor::new());
//!
//!     // Creates a new server
//!     let listener = TcpListener::bind("127.0.0.1:60000").await.unwrap();
//!     let config = ServerConfig::default();
//!     let server = Server::new(listener, config, ex.clone());
//!
//!     // Register the HelloWorld service
//!     register_service!(HelloWorld, say_hello);
//!     server.attach_service(HelloWorld{});
//!
//!     // Starts the server
//!     ex.run(server.start());
//! };
//!
//! // Client
//! async {
//!
//!     // Creates a new client
//!     let conn = TcpStream::connect("127.0.0.1:60000").await.unwrap();
//!     let config = ClientConfig::default();
//!     let client = Client::new(conn, config);
//!
//!     let result: String = client.call("HelloWorld.say_hello", "world".to_string()).await.unwrap();
