how to draw https://docs.rs/wgpu/latest/wgpu/struct.Texture.html in egui ?

[m172021]

I have a wgpu::Texture . I want to draw it in a egui::Image . How do I do that ?

1. Background: I have my own wgpu code, which I am integrating with egui. I have eframe running with features "wgpu". This allows me to do CreationContext -> WgpuRenderState via https://docs.rs/eframe/latest/eframe/struct.CreationContext.html#structfield.wgpu_render_state

2. Using the wgpu_render_state, I can initialize my own wgpu code. Then I do some drawing in wgpu land, and I render to a https://docs.rs/wgpu/latest/wgpu/struct.Texture.html

3. Now, I need to take this Texture and render it someone in egui.

4. The obvious thing to try is https://docs.rs/egui/latest/egui/enum.TextureId.html . In particular,

let id : u64 = ???;
                    let img = egui::Image::from_texture(egui::load::SizedTexture::new(egui::TextureId::User(id), [300.0, 300.0]));
                    ui.add(img);

5. Now, my question: I have a wgpu::Texture . How do I convert it to a u64 ?

Thanks!
