That's about one order of magnitude smaller than Electron. Good to know.
My gtk-rs project is intended to replace a small, self contained win32 application. The application is 132KB. So although 5MB is small it's an oom larger than my benchmark.
However, my gtk-rs hello, world GUI application is 14.6MB in release mode and that does not include the GTK DLLs that are also needed. Yikes. That's crazy.
Perhaps 5MB is a reasonable price to pay for cross platform GUI. Not taking 7+ seconds to build a GUI hello, world would be nice as well.
