Update of the state of built-in debugging facilities.

Variants

SetFlags(DebugFlags)

Sets the provided debug flags.

GetDebugFlags(Sender<DebugFlags>)

Get current debug flags

SaveCapture(PathBuf, CaptureBits)

Save a capture of all the documents state.

LoadCapture(PathBuf, Option<(u32, u32)>, Sender<CapturedDocument>)

Load a capture of all the documents state.

StartCaptureSequence(PathBuf, CaptureBits)

Start capturing a sequence of scene/frame changes.

StopCaptureSequence

Stop capturing a sequence of scene/frame changes.

ClearCaches(ClearCache)

Clear cached resources, forcing them to be re-uploaded from templates.

EnableNativeCompositor(bool)

Enable/disable native compositor usage

SetBatchingLookback(u32)

Sets the maximum amount of existing batches to visit before creating a new one.

InvalidateGpuCache

Invalidate GPU cache, forcing the update from the CPU mirror.

SimulateLongSceneBuild(u32)

Causes the scene builder to pause for a given amount of milliseconds each time it processes a transaction.

SetPictureTileSize(Option<DeviceIntSize>)

Set an override tile size to use for picture caches

SetMaximumSurfaceSize(Option<usize>)

Set an override for max off-screen surface size

GenerateFrame

Generate a frame to force a redraw / recomposite
