Debug options for Servo, currently set on the command line with -Z

Fields

help: bool

List all the debug options.

dump_style_tree: bool

Print the DOM after each restyle.

dump_rule_tree: bool

Dumps the rule tree.

dump_flow_tree: bool

Print the fragment tree after each layout.

dump_stacking_context_tree: bool

Print the stacking context tree after each layout.

dump_scroll_tree: bool

Print the scroll tree after each layout.

dump_display_list: bool

Print the display list after each layout.

relayout_event: bool

Print notifications when there is a relayout.

profile_script_events: bool

Periodically print out on which events script threads spend their processing time.

trace_layout: bool

True if each step of layout is traced to an external JSON file for debugging purposes. Setting this implies sequential layout and paint.

disable_share_style_cache: bool

Disable the style sharing cache.

dump_style_statistics: bool

Whether to show in stdout style sharing cache stats after a restyle.

convert_mouse_to_touch: bool

Translate mouse input into touch events.

gc_profile: bool

Log GC passes and their durations.

webrender_stats: bool

Show webrender profiling stats on screen.

signpost: bool

True to use OS native signposting facilities. This makes profiling events (script activity, reflow, compositing, etc.) appear in Instruments.app on macOS.
