//! WebSocket echo server example
//!
//! This example demonstrates how to create a WebSocket server that accepts
//! incoming connections and echoes messages back to clients.
//!
//! Run with:
//! ```sh
//! cargo run --example socket_server --features tungstenite
//! ```
//! Test with a WebSocket client:
//! ```sh
//! # In another terminal, run the echo endpoint test
//! cargo run --example socket_client --features tungstenite
//! ```
