Arrow Display

Arrow Display is a Rust Application used to display the current speed digitally.

Prerequisites

• Rust 1.36 or higher
• Cargo (Comes with Rust installation)

Installation

1. Clone the repo: git clone git@github.com:team-arrow-racing/arrow_display.git
2. Move into the newly created directory: cd arrow_display

Running

After you cloned the repository you can run the application by typing the following command into your terminal:

cargo run

The application will run on an infinite loop, displaying a random current speed every second. To stop the execution, use Ctrl + C keys.

Testing

Use cargo to run the predefined tests:

cargo test

The current test examines the show_speed functionality in speed_display.rs.

Documentation

The application consists of the following files:

• main.rs: Entry point of the application. It creates the display, a SpeedDisplay object and handles user events and window updates. It simulates the current speed with a random number generator.
• speed_display.rs: Contains the SpeedDisplay struct and its associated methods. SpeedDisplay::show_speed handles the graphical display of the current speed.
• speed_display_test.rs: Contains the tests for the SpeedDisplay struct.

External Dependencies

• embedded-graphics for rendering the graphical user interface
• embedded-graphics-simulator for simulating the display
• rand for generating random current speeds
