//! This example demonstrates how to serve embedded files from the file system over HTTP.
//!
//! # Run the example
//!
//! ```sh
//! cargo run --example http_service_include_dir --features=http-full
//! ```
//!
//! # Expected output
//!
//! The server will start and listen on `:62037`.
//! You can use your browser to interact with the service:
//!
//! ```sh
//! curl -v http://127.0.0.1:62037
//! ```
//!
//! You should see a response with `HTTP/1.1 200 OK` and the content of the `index.html` file.
