//! A fast and lightweight async [JSONRPC 2.0](https://www.jsonrpc.org/specification) implementation.
//!
//! # Example
//!
//! ```
//! use std::sync::Arc;
//!
//! use serde_json::Value;
//!
//! use karyons_jsonrpc::{JsonRPCError, Server, Client, register_service};
//!
//! 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 endpoint = "tcp://127.0.0.1:60000".parse().unwrap();
//! let server = Server::new_with_endpoint(&endpoint, ex.clone()).await.unwrap();
//!
//! // 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 endpoint = "tcp://127.0.0.1:60000".parse().unwrap();
//! let client = Client::new_with_endpoint(&endpoint, None).await.unwrap();
//!
//! let result: String = client.call("HelloWorld.say_hello", "world".to_string()).await.unwrap();
//! };
//!
//! ```
