This is the egui integration crate for egui-winit and ash. The default GPU allocator is gpu_allocator, but you can also implement AllocatorTrait.
This crate does not support multi-viewports for multi-window since version 0.24 of egui.
egui-ash is an alternative crate, which supports multi-viewports, so please take a look at this one.
