//! A fast and lightweight async implementation of [JSON-RPC
//! 2.0](https://www.jsonrpc.org/specification).
//!
//! features:
//! - Supports TCP, TLS, WebSocket, and Unix protocols.
//! - Uses smol(async-std) as the async runtime, but also supports tokio via
//! the `tokio` feature.
//! - Allows registration of multiple services (structs) of different types on a
//! single server.
//!
//! # Example
//!
//! ```
//! use std::sync::Arc;
//!
//! use serde_json::Value;
//! use smol::net::{TcpStream, TcpListener};
//!
//! use karyon_jsonrpc::{Error, Server, Client, rpc_impl};
//!
//! struct HelloWorld {}
//!
//! #[rpc_impl]
//! impl HelloWorld {
//! async fn say_hello(&self, params: Value) -> Result<Value, Error> {
//! let msg: String = serde_json::from_value(params)?;
//! Ok(serde_json::json!(format!("Hello {msg}!")))
//! }
//!
//! async fn foo(&self, params: Value) -> Result<Value, Error> {
//! Ok(serde_json::json!("foo!"))
//! }
//!
//! async fn bar(&self, params: Value) -> Result<Value, Error> {
//! Ok(serde_json::json!("bar!"))
//! }
//! }
//!
//! // Server
//! async {
//! // Creates a new server
//! let server = Server::builder("tcp://127.0.0.1:60000")
//! .expect("create new server builder")
//! .service(HelloWorld{})
//! .build()
//! .await
//! .expect("build the server");
//!
//! // Starts the server
//! server.start().await.expect("start the server");
//! };
//!
//! // Client
//! async {
//! // Creates a new client
//! let client = Client::builder("tcp://127.0.0.1:60000")
//! .expect("create new client builder")
//! .build()
//! .await
//! .expect("build the client");
//!
//! let result: String = client.call("HelloWorld.say_hello", "world".to_string())
//! .await
//! .expect("send a request");
//! };
//!
