# Hospital API

A Rust-based API service that manages and provides information about hospitals on duty in Luxembourg City.

## Overview

This API service tracks which hospital is currently on duty in Luxembourg City and provides endpoints to access this information. The system automatically manages hospital shifts and ensures there's always a hospital assigned for emergency services.

## Features

- **Automatic Shift Management**: Creates and manages hospital shifts automatically
- **Real-time Hospital Information**: Provides current on-duty hospital information via API
- **Periodic Checks**: Regularly verifies and updates future shifts
- **Timestamped Logging**: All system events are logged with timestamps for better tracking
