Mastrena 3.0

Overview

Mastrena 3.0 is an espresso machine simulation system built with Rust. This project provides a RESTful API to simulate espresso extraction processes with customizable parameters such as temperature, pressure, and extraction time. The system also records extraction metrics for future analysis.

Features

• Espresso Extraction Simulation: Simulates the brewing process with adjustable settings.
• Customizable Parameters: Users can define temperature, pressure, and extraction time.
• Validation Mechanism: Ensures input values fall within realistic ranges.
• Metrics Storage: Records extraction data in JSON format for future reference.
• REST API: Provides endpoints to start an extraction and retrieve past records.

Installation

To set up Mastrena 3.0, follow these steps:

1. Clone the repository:

   git clone https://github.com/beltradini/mastrena-3.0.git
   cd mastrena-3.0

2. Install Rust (if not already installed):

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

3. Build and run the project:

   cargo run

API Endpoints

Start an Espresso Extraction

POST /start

Query Parameters:

• temperature (optional, default: 93.0°C)
• pressure (optional, default: 9.0 bar)
• time_seconds (optional, default: 25s)

Example:

curl -X POST "http://127.0.0.1:3000/start?temperature=95&pressure=9.5&time_seconds=27"

Retrieve Extraction Metrics

GET /metrics

Example:

curl -X GET "http://127.0.0.1:3000/metrics"

Future Improvements

• Implement a database for better storage and retrieval of metrics.
• Add support for different espresso recipes.
• Enhance error handling and logging.
• Expand API functionalities with additional beverage simulations.
