iced-rs/iced

Iced is a library for building graphical desktop applications in Rust. It solves the problem of creating native user interfaces, windows, buttons, text fields, layouts, in a language that historically lacked good options for this. Iced targets Windows, macOS, Linux, and the web from a single codebase. The design is inspired by Elm, a functional programming language with an architecture that keeps application logic predictable. In practice this means a developer defines their application around four concepts: the data the app holds (called State), the events the user can trigger (Messages), how to display the data as visual elements (View logic), and how to update the data when an event occurs (Update logic). The library handles the loop of drawing the interface, listening for input, calling the update function, and redrawing, the developer only writes the data and the responses to events. Under the hood, Iced can render using two different graphics backends: one that uses wgpu (which runs on Vulkan, Metal, and DX12, the low-level graphics APIs for Windows, Mac, and Linux respectively), and a software-based fallback for environments where hardware acceleration is unavailable. A Rust developer would use Iced when building a desktop application that needs a real graphical interface, a configuration tool, a file manager, an IRC client (the README shows one as an example), and wants to stay entirely within the Rust ecosystem. The README notes it is currently experimental software. It is written in Rust and available as a package on crates.io, the standard Rust package registry.
