Fields

textures: Vec<PictureTexture>

Current list of textures in the pool

default_tile_size: DeviceIntSize

Default tile size for content tiles

allocated_texture_count: usize

Number of currently allocated textures in the pool

filter: TextureFilter

Texture filter to use for picture cache textures

debug_flags: DebugFlags

cache_entries: FreeList<PictureCacheEntry, PictureCacheEntryMarker>

Cache of picture cache entries.

cache_handles: Vec<FreeListHandle<PictureCacheEntryMarker>>

Strong handles for the picture_cache_entries FreeList.

now: FrameStamp

Implementations

impl PictureTextures

pub fn new(default_tile_size: DeviceIntSize, filter: TextureFilter) -> Self

pub fn begin_frame( &mut self, stamp: FrameStamp, pending_updates: &mut TextureUpdateList )

pub fn default_tile_size(&self) -> DeviceIntSize

pub fn update( &mut self, tile_size: DeviceIntSize, handle: &mut Option<WeakFreeListHandle<PictureCacheEntryMarker>>, gpu_cache: &mut GpuCache, next_texture_id: &mut CacheTextureId, pending_updates: &mut TextureUpdateList )

pub fn get_or_allocate_tile( &mut self, tile_size: DeviceIntSize, next_texture_id: &mut CacheTextureId, pending_updates: &mut TextureUpdateList ) -> WeakFreeListHandle<PictureCacheEntryMarker>

pub fn free_tile( &mut self, id: CacheTextureId, current_frame_id: FrameId, pending_updates: &mut TextureUpdateList )

pub fn request( &mut self, handle: &WeakFreeListHandle<PictureCacheEntryMarker>, gpu_cache: &mut GpuCache ) -> bool

pub fn get_texture_source( &self, handle: &WeakFreeListHandle<PictureCacheEntryMarker> ) -> TextureSource

pub fn expire_old_tiles(&mut self, pending_updates: &mut TextureUpdateList)

Expire picture cache tiles that haven’t been referenced in the last frame. The picture cache code manually keeps tiles alive by calling request on them if it wants to retain a tile that is currently not visible.

pub fn clear(&mut self, pending_updates: &mut TextureUpdateList)

pub fn update_profile(&self, profile: &mut TransactionProfile)

pub fn gc(&mut self, pending_updates: &mut TextureUpdateList)

Simple garbage collect of picture cache tiles

pub fn entry_exists( &self, handle: &WeakFreeListHandle<PictureCacheEntryMarker> ) -> bool

pub fn set_debug_flags(&mut self, flags: DebugFlags)

Trait Implementations

impl Serialize for PictureTextures

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
