Internet Speed Test

Description

This is a simple but effective internet speed test application built with Rust. It measures your download speed by downloading files of various sizes from a Hetzner server. The application calculates the average, minimum, and maximum download speeds and displays the results in the console. It also saves the results to a JSON file for later analysis.

Usage

The application is controlled via the command line. Here are the available commands:

• internet_speed_test test: Runs the speed test.
  • --size <file_size>: The size of the file to download. Available options are 100MB, 1GB, and 10GB. Defaults to 100MB.
  • --duration <seconds>: The duration of the test in seconds. Defaults to 10.
• internet_speed_test about: Shows a description of the application.
• internet_speed_test version: Shows the application version.

Example

internet_speed_test test --size 1GB --duration 20

How it Works

The application works by performing the following steps:

1. Parsing Command-Line Arguments: The application uses the clap crate to parse command-line arguments and subcommands.
2. Running the Speed Test: The test command runs the core speed test logic. This function downloads a file from a specified URL for a given duration. It uses the reqwest crate to make HTTP requests and the indicatif crate to display a progress bar.
3. Calculating Speed: The application calculates the download speed in megabits per second (Mbps). It also keeps track of the minimum and maximum speeds recorded during the test.
4. Displaying Results: After the test is complete, the application displays the results in the console. This includes the total data downloaded, the total time elapsed, the average download speed, and the minimum and maximum chunk speeds.
5. Saving Results: The application saves the results to a JSON file named speed_test_results.json. This file includes a timestamp, the test parameters, and the detailed results.
