Struct ExternalNativeSurface 

Source 
pub struct ExternalNativeSurface {
    pub used_this_frame: bool,
    pub native_surface_id: NativeSurfaceId,
    pub image_dependencies: [ImageDependency; 3],
}
Expand description

Information about a native compositor surface cached between frames.

Fields§

§used_this_frame: bool

If true, the surface was used this frame. Used for a simple form of GC to remove old surfaces.

§native_surface_id: NativeSurfaceId

The native compositor surface handle

§image_dependencies: [ImageDependency; 3]

List of image keys, and current image generations, that are drawn in this surface. The image generations are used to check if the compositor surface is dirty and needs to be updated.
