Implementations

impl GlTextureCache

pub fn empty() -> Self

Initializes an empty cache

pub fn new( layout_results: &mut [LayoutResult], gl_context: &OptionGlContextPtr, id_namespace: IdNamespace, document_id: &DocumentId, epoch: Epoch, hidpi_factor: f32, image_cache: &ImageCache, system_fonts: &FcFontCache, callbacks: &RenderCallbacks, all_resource_updates: &mut Vec<ResourceUpdate>, renderer_resources: &mut RendererResources, ) -> Self

Invokes all ImageCallbacks with the sizes given by the LayoutResult and adds them to the RendererResources.

pub fn update_texture( &mut self, dom_id: DomId, node_id: NodeId, document_id: DocumentId, epoch: Epoch, new_texture: Texture, callbacks: &RenderCallbacks, ) -> Option<ExternalImageId>

Updates a given texture
