Struct DisplayListParametersRef

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 gl_texture_cache: &'a GlTextureCache,
    pub image_cache: &'a ImageCache,
    pub renderer_resources: &'a RendererResources,
}

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

Trait Implementations

impl<'a> Clone for DisplayListParametersRef<'a>

fn clone(&self) -> DisplayListParametersRef<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
