Expand description
The main LRU cache interface.
Fields§
§now: FrameStamp
Current FrameId.
texture: Texture
CPU-side texture allocator.
saved_block_count: usize
Number of blocks requested this frame that don’t need to be re-uploaded.
debug_flags: DebugFlags
The current debug flags for the system.
pending_clear: bool
Whether there is a pending clear to send with the next update.
prepared_for_frames: bool
Indicates that prepare_for_frames has been called for this group of frames. Used for sanity checks.
requires_frame_build: bool
This indicates that we performed a cleanup operation which requires all documents to build a frame.
document_frames_to_build: HashSet<DocumentId, BuildHasherDefault<FxHasher>>
The set of documents which have had frames built in this update. Used for sanity checks.
Implementations§
source§impl GpuCache
impl GpuCache
pub fn new() -> Self
sourcepub fn clear(&mut self)
pub fn clear(&mut self)
Drops everything in the GPU cache. Must not be called once gpu cache entries for the next frame have already been requested.
pub fn requires_frame_build(&self) -> bool
pub fn prepare_for_frames(&mut self)
pub fn bookkeep_after_frames(&mut self)
sourcepub fn begin_frame(&mut self, stamp: FrameStamp)
pub fn begin_frame(&mut self, stamp: FrameStamp)
Begin a new frame.
pub fn invalidate(&mut self, handle: &GpuCacheHandle)
sourcepub fn request<'a>(
&'a mut self,
handle: &'a mut GpuCacheHandle
) -> Option<GpuDataRequest<'a>>
pub fn request<'a>( &'a mut self, handle: &'a mut GpuCacheHandle ) -> Option<GpuDataRequest<'a>>
Request a resource be added to the cache. If the resource
is already in the cache, None
will be returned.
pub fn push_per_frame_blocks( &mut self, blocks: &[GpuBlockData] ) -> GpuCacheHandle
pub fn push_deferred_per_frame_blocks( &mut self, block_count: usize ) -> GpuCacheHandle
sourcepub fn end_frame(&mut self, profile: &mut TransactionProfile) -> FrameStamp
pub fn end_frame(&mut self, profile: &mut TransactionProfile) -> FrameStamp
End the frame. Return the list of updates to apply to the device specific cache texture.
sourcepub fn should_reclaim_memory(&self) -> bool
pub fn should_reclaim_memory(&self) -> bool
Returns true if utilization has been low enough for long enough that we should blow the cache away and rebuild it.
sourcepub fn extract_updates(&mut self) -> GpuCacheUpdateList
pub fn extract_updates(&mut self) -> GpuCacheUpdateList
Extract the pending updates from the cache.
sourcepub fn set_debug_flags(&mut self, flags: DebugFlags)
pub fn set_debug_flags(&mut self, flags: DebugFlags)
Sets the current debug flags for the system.
sourcepub fn get_address(&self, id: &GpuCacheHandle) -> GpuCacheAddress
pub fn get_address(&self, id: &GpuCacheHandle) -> GpuCacheAddress
Get the actual GPU address in the texture for a given slot ID. It’s assumed at this point that the given slot has been requested and built for this frame. Attempting to get the address for a freed or pending slot will panic!
