Render buffer as image

[guerinoni]

I'm writing an emulator and I need to render on-screen a buffer like Vec... How I can do this? Using egui::Image? Or Texture? I'm reading all docs but I don't have found anything related.
Thanks in advance

Are you using eframe? If so, use the texture allocator: https://docs.rs/epi/0.14.0/epi/struct.Frame.html#method.tex_allocator together with egui::Image

Can you provide a simple example??
If I have something like

const WIDTH: usize = 640;
const HEIGHT: usize = 360;
let mut buffer: Vec<u32> = vec![0; WIDTH * HEIGHT];

Now I'm searching for a sort of window.update(buffer)

Here is an example of loading an image: https://github.com/emilk/egui/blob/master/examples/retained_image/src/main.rs
