Struct GpuOptions 

#[non_exhaustive]
pub struct GpuOptions {
    pub transparent: bool,
}

How a Gpu is opened: what its surfaces must be able to do, decided before the first one exists because some of it is the instance’s.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

transparent: bool

Its surfaces may be presented with alpha (Renderer::new_in_with, Renderer::transparent), so a window shows what is behind it where a frame paints nothing (backlog F126). On Windows this presents D3D12 through DirectComposition (Dx12SwapchainKind::DxgiFromVisual), the one D3D12 swapchain that takes alpha, instead of a swapchain on the window’s handle — where see_through_by_visual says the window was made for it, and nowhere else, so there the surfaces stay opaque otherwise; nothing changes on other platforms. Off by default, so an opaque app keeps the swapchain it always had.
