Xilem: An Experimental Rust Architecture for Reactive UI Development

Xilem and Masonry are pioneering frameworks designed to facilitate the creation of GUI applications in Rust. Masonry acts as a foundational toolkit, providing a retained widget tree and managing event handling and updates. Xilem, on the other hand, is a high-level reactive framework inspired by popular frameworks like React, SwiftUI, and Elm. It allows developers to construct a lightweight view tree that dynamically updates the rendered application based on changes to this tree. Xilem supports both web and Masonry backends, making it versatile for different development needs.

For those new to these tools, Xilem is recommended for its simplicity and ease of use, especially if the goal is to develop an application with minimal complexity. Masonry, however, serves as a robust toolkit for building UI frameworks, including Xilem itself.

To get started with Xilem, developers can clone the repository and run examples such as the 'to_do_mvc'. Adding Xilem to a project is straightforward with the command 'cargo add xilem'. The framework requires certain prerequisites on Linux and BSD systems, including packages like pkg-config, clang, and others specific to the distribution.

The project encourages community involvement through discussions on Linebender Zulip and welcomes contributions via pull requests, adhering to the Rust code of conduct. The framework is licensed under the Apache License, Version 2.0, with some example files under different licenses.

Xilem's development environment is optimized for Linux and macOS, with recommendations for using split-debuginfo to manage dependency sizes. The minimum supported Rust version is 1.92, with future updates potentially requiring newer versions without being considered breaking changes.
