Fields

state: Option<i32>

reason: Option<i32>

The reason is set only if |state| is not |STATE_UPDATED_ALL|.

frame_source: Option<u64>

frame_sequence: Option<u64>

affects_smoothness: Option<bool>

If this is a droped frame (i.e. if |state| is set to |STATE_DROPPED| or |STATE_PRESENTED_PARTIAL|), then indicates whether this frame impacts smoothness.

scroll_state: Option<i32>

The type of active scroll.

has_main_animation: Option<bool>

If any main thread animation is active during this frame.

has_compositor_animation: Option<bool>

If any compositor thread animation is active during this frame.

has_smooth_input_main: Option<bool>

If any touch-driven UX (not scroll) is active during this frame.

has_missing_content: Option<bool>

Whether the frame contained any missing content (i.e. whether there was checkerboarding in the frame). If has_missing_content, checkerboarded_needs_raster and checkerboarded_needs_record all have values, has_missing_content should equal checkerboarded_needs_raster || checkerboarded_needs_record.

layer_tree_host_id: Option<u64>

The id of layer_tree_host that the frame has been produced for.

has_high_latency: Option<bool>

If total latency of PipelineReporter exceeds a certain limit.

frame_type: Option<i32>

Indicate if the frame is “FORKED” (i.e. a PipelineReporter event starts at the same frame sequence as another PipelineReporter) or “BACKFILL” (i.e. dropped frames when there are no partial compositor updates).

high_latency_contribution_stage: Vec<String>

The breakdown stage of PipelineReporter that is most likely accountable for high latency.

checkerboarded_needs_raster: Option<bool>

Whether the frame contained any content that is not fully rastered.

checkerboarded_needs_record: Option<bool>

Whether the frame contained any content that is not fully recorded.
