//! 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");
//! };
