lsg is a library for making desktop/mobile gui applications in rust
It has a lot of other features that make it awesome:
- many very functional builtin widgets
- make it easy and pleasant to style widgets yourself
- fully controllable semi-automatic layouting that makes sense
- ergonomic async support that can abstract away your typical event loop
- you can tightly associate widgets with your application state
- gpu accelerated drawing (using OpenGL)
This library requires the use of async rust to handle events. This provides a very
powerful architecture and means your ui and logic can run on the same thread.
We also don't force any async runtime upon you. You can use smol, tokio or even just futures-lite.
It is recommended to use a runtime that let's you spawn tasks though, because this let's you handle events
in a really ergonomic way.
In my opinion smol/async-executor is the best choice, since it fits into this crates lightweight philosophy.
Being "light" means following things:
- short incremental compilation times (for rust standards)
- fast, even in debug builds
- reasonably small executable size
lsg keeps it's dependencies minimal. However this also means that the library itself is missing
some features you would expect in a traditional gui framework, notably we don't have builtin support for:
- a lot of image formats (only png is included)
- a lot of font formats (only ttf/otf is included)
- platform specific api's
These features should be implemented in the future:
- support for accesskit
- drag and drop
- more platforms
Currently this library supports:
- Linux (Wayland or X11)
- Windows
Will be implemented in the future:
- Android
Will not be implemented:
- MacOs / iOS
