Struct RendererResources 

pub struct RendererResources { /* private fields */ }

Renderer resources that manage font, image and font instance keys. RendererResources are local to each renderer / window, since the keys are not shared across renderers

The resources are automatically managed, meaning that they each new frame (signified by start_frame_gc and end_frame_gc)

Implementations

impl RendererResources

pub fn get_image(&self, hash: &ImageRefHash) -> Option<&ResolvedImage>

pub fn get_font_family( &self, style_font_families_hash: &StyleFontFamiliesHash, ) -> Option<&StyleFontFamilyHash>

pub fn get_font_key( &self, style_font_family_hash: &StyleFontFamilyHash, ) -> Option<&FontKey>

pub fn get_registered_font( &self, font_key: &FontKey, ) -> Option<&(FontRef, FastHashMap<(Au, DpiScaleFactor), FontInstanceKey>)>

pub fn update_image( &mut self, image_ref_hash: &ImageRefHash, descriptor: ImageDescriptor, )

pub fn do_gc( &mut self, all_resource_updates: &mut Vec<ResourceUpdate>, css_image_cache: &ImageCache, new_layout_results: &[LayoutResult], gl_texture_cache: &GlTextureCache, )

Updates the internal cache, adds ResourceUpdate::Remove() to the all_resource_updates

This function will query all current images and fonts submitted into the cache and set them for the next frame so that unused resources will be cleaned up.

This function should be called after the StyledDom has been exchanged for the next frame and AFTER all OpenGL textures and image callbacks have been resolved.

pub fn rerender_image_callback( &mut self, dom_id: DomId, node_id: NodeId, document_id: DocumentId, epoch: Epoch, id_namespace: IdNamespace, gl_context: &OptionGlContextPtr, image_cache: &ImageCache, system_fonts: &FcFontCache, hidpi_factor: f32, callbacks: &RenderCallbacks, layout_results: &mut [LayoutResult], gl_texture_cache: &mut GlTextureCache, ) -> Option<UpdateImageResult>

pub fn update_image_resources( &mut self, layout_results: &[LayoutResult], images_to_update: BTreeMap<DomId, BTreeMap<NodeId, (ImageRef, UpdateImageType)>>, image_masks_to_update: BTreeMap<DomId, BTreeMap<NodeId, ImageMask>>, callbacks: &RenderCallbacks, image_cache: &ImageCache, gl_texture_cache: &mut GlTextureCache, document_id: DocumentId, epoch: Epoch, ) -> Vec<UpdateImageResult>
