## What it is
Rust bindings for the FLTK 1.4 cross-platform GUI library, providing around 80 customizable widgets with static linking support. It produces small, self-contained, fast desktop applications without external DLL dependencies.

## Use cases
- build a lightweight desktop gui app in rust
- create cross-platform native widgets application
- make a small single-executable gui tool with no dlls
- build a themed desktop application with gtk or plastic look
- write a fast-startup gui utility in rust
- embed images and custom widgets in a rust desktop app

## When to choose
- you need small binaries and low memory footprint
- you want statically linked single-executable gui apps
- you need to support old architectures
- you want fast build and startup times
- you need permissive licensing for closed-source static linking

## When to avoid
- you need modern gpu-accelerated rendering or rich animations
- you want a web-based or mobile gui
- you need extensive ecosystem and theming beyond fltk's schemes
- you prefer declarative/immediate-mode ui paradigms like egui

## Facets
- artifact type: library
- maturity: active
- function: gui, ui-components, graphics
- domain: desktop-applications, cross-platform, developer-tools
- platform: cross-platform, windows, rust
- tags: fltk, gui-toolkit, widgets, bindings, static-linking, lightweight, linux, macos
