# guiver
GUI programming with Rust.
guiver can be used in immediate mode, which is inspired by [egui](https://github.com/emilk/egui). In this case it is
just a thin wrapper around [druid-shell](https://github.com/linebender/druid/tree/master/druid-shell) for event
handling/windowing and [Piet](https://github.com/linebender/piet) for rendering.
There are retained mode widgets that can be used with the help of an optional widget manager.
The widgets are decoupled from the application data via message passing, which is inspired by
[Tk commands](https://en.wikipedia.org/wiki/Tk_(software)) and egui.
