Cushy

Cushy is considered alpha and unsupported crate version Documentation for main Cushy User's Guide

Cushy is an experimental Graphical User Interface (GUI) crate for the Rust programming language. It features a reactive data model and aims to enable easily creating responsive, efficient user interfaces. To enable easy cross-platform development, Cushy uses its own collection of consistently-styled Widgets.

Cushy is powered by:

Getting Started with Cushy

The Widget trait is the building block of Cushy: Every user interface element implements Widget. The Widget trait documentation has an overview of how Cushy works. A list of built-in widgets can be found in the cushy::widgets module.

Cushy uses a reactive data model. To see an example of how reactive data models work, consider this example that displays a button that increments its own label:

fn main() -> cushy::Result {
    // Create a dynamic usize.
    let count = Dynamic::new(0_isize);

    // Create a new label displaying `count`
    count
        .to_label()
        // Use the label as the contents of a button
        .into_button()
        // Set the `on_click` callback to a closure that increments the counter.
        .on_click(move |_| count.set(count.get() + 1))
        // Run the application
        .run()
}

Here are some ways to learn more about Cushy:

  • Explore the examples directory. Nearly every feature in Cushy was initially tested by creating an example. Many are focused on demonstrating a single feature, but there are some complex example such as a theme editor/previewer:

  • Browse the user's guide. The user guide is a work in progress, but features CI-generated screenshots and animations for its examples:

  • Ask questions in Discussions or on Discord.

Project Status

This project is early in development, but is quickly becoming a decent framework. It is considered alpha and unsupported at this time, and the primary focus for @ecton is to use this for his own projects. Feature requests and bug fixes will be prioritized based on @ecton's own needs.

If you would like to contribute, bug fixes are always appreciated. Before working on a new feature, please open an issue proposing the feature and problem it aims to solve. Doing so will help prevent friction in merging pull requests, as it ensures changes fit the vision the maintainers have for Cushy.
