Struct BlendModeValues 

pub struct BlendModeValues {
    pub premultiplied: Option<u64>,
    pub coverage: Option<u64>,
    pub none: Option<u64>,
}

Driver-assigned enum integers for a property’s named values.

The kernel hands back enum values in the order the driver registered them, so a caller must look up by name and cache the integer — which is what this holds. None means the plane does not advertise that value at all.

Fields

premultiplied: Option<u64>

"Pre-multiplied". Prefer this: it matches the canvas’s premultiplied output convention.

coverage: Option<u64>

"Coverage" — straight-alpha SRC_OVER.

none: Option<u64>

"None" — pixel replace, no blending.
