usenet-dl 0.4.0

//! REST API server example
//!
//! This example shows how to run usenet-dl with the REST API enabled,
//! allowing control via HTTP endpoints.
//!
//! After starting, you can:
//! - View Swagger UI at http://localhost:6789/swagger-ui
//! - Add downloads via POST http://localhost:6789/api/v1/downloads/url
//! - Monitor progress via GET http://localhost:6789/api/v1/downloads
//! - Stream events via GET http://localhost:6789/api/v1/events
