Building cross-platform GUI apps in Rust using egui

The article explores the limitations and potential of using the Rust-based library egui to build cross-platform GUI applications, highlighting its immediate mode GUI framework that offers simplicity and responsiveness, albeit with some trade-offs in complex layout handling. The piece describes the process of creating a simple pet management application, leveraging egui for its ease of use and modularity, and employing an sqlite database for data storage. The application features a user interface with a list of pets and detailed views, utilizing APIs for random pet images and demonstrating the immediate mode's synchronous interaction benefits. The article also discusses event handling with multithreading to maintain UI responsiveness and concludes by noting egui's promising ecosystem for Rust GUI development, supported by extensive documentation and examples.
