Ply: A New Era for Cross-Platform App Development in Rust

The Challenge of Building in Rust

Building applications in Rust can often feel like navigating a labyrinth. For one developer, the journey began with a desire to create a multiplayer board game, complete with a server, client, and a shared crate for game logic. However, as they ventured into existing frameworks like Bevy, Iced, and egui, they quickly encountered a series of roadblocks. Bevy's complex ECS model turned simple tasks into convoluted queries, while Iced's syntax was riddled with confusing defaults. Even the promising Slint fell short due to its separate markup language, making integration into existing Rust codebases a hassle.

The frustration didn’t stop there. Attempts to utilize macroquad, which promised cross-platform capabilities, revealed its limitations as merely a rendering library without a robust app engine. The developer's quest for a streamlined solution led them to explore Clay, a C layout library, but this too resulted in a series of bugs and limitations, including issues with texture management and a lack of fundamental graphics operations like rotation. It became clear: a new solution was needed.

The Birth of Ply

In response to these challenges, the developer embarked on a mission to create Ply, a cross-platform app framework built entirely in Rust. The goal was to craft a clean and efficient architecture that would allow developers to write applications without the headaches associated with existing tools. After extensive analysis of various UI frameworks, including Iced, egui, and Qt/QML, the developer identified key strengths and weaknesses, ultimately shaping the vision for Ply's API.

By February, the focus shifted to porting the layout engine to 100% Rust. This transition not only improved performance but also allowed for a more intuitive API design. The new framework employs a builder pattern combined with closures, addressing common frustrations such as the cumbersome .end() calls and scattered default specifications. With Ply, developers can now chain method calls like .shader() and choose between .degrees() or .radians(), all while maintaining code readability.

What This Means for Practitioners

For software engineers and ML practitioners, Ply represents a significant step forward in Rust app development. The framework’s emphasis on clean architecture and usability allows developers to focus on building features rather than wrestling with convoluted syntax. With built-in support for shaders, accessibility, and networking, Ply is poised to become a go-to solution for those looking to create cross-platform applications efficiently.

As the landscape of app development continues to evolve, Ply stands out as a promising alternative for Rust enthusiasts. It has the potential to streamline workflows, reduce development time, and ultimately empower developers to bring their ideas to life without the usual headaches. In a world where time is money, Ply could be the key to unlocking faster, more enjoyable app development experiences.
