Struct DisplayListParametersRef

Source
pub struct DisplayListParametersRef<'a> {
    pub dom_id: DomId,
    pub document_id: &'a DocumentId,
    pub epoch: Epoch,
    pub full_window_state: &'a FullWindowState,
    pub layout_results: &'a [LayoutResult],

    pub image_cache: &'a ImageCache,
    pub renderer_resources: &'a RendererResources,
}
Expand description

Since the display list can take a lot of parameters, we don’t want to continually pass them as parameters of the function and rather use a struct to pass them around. This is purely for ergonomic reasons.

DisplayListParametersRef has only members that are immutable references to other things that need to be passed down the display list

Fields§

§dom_id: DomId

ID of this Dom

§document_id: &'a DocumentId

Document ID (window ID)

§epoch: Epoch

Epoch of all the OpenGL textures

§full_window_state: &'a FullWindowState

The CSS that should be applied to the DOM

§layout_results: &'a [LayoutResult]

Cached layouts (+ solved layouts for iframes)

§gl_texture_cache: &'a GlTextureCache

Cached rendered OpenGL textures

§image_cache: &'a ImageCache

Cached IDs for CSS backgrounds

§renderer_resources: &'a RendererResources

Reference to the RendererResources, necessary to query info about image and font keys
