Statistics gathered during the traversal plus some information from other sources including stylist.

Fields

aggregated: PerThreadTraversalStatistics

Aggregated statistics gathered during the traversal.

selectors: u32

The number of selectors in the stylist.

revalidation_selectors: u32

The number of revalidation selectors.

dependency_selectors: u32

The number of state/attr dependencies in the dependency set.

declarations: u32

The number of declarations in the stylist.

stylist_rebuilds: u32

The number of times the stylist was rebuilt.

traversal_time_ms: f64

Time spent in the traversal, in milliseconds.

is_parallel: bool

Whether this was a parallel traversal.

is_large: bool

Whether this is a “large” traversal.

Implementations

impl TraversalStatistics

pub fn new<E, D>( aggregated: PerThreadTraversalStatistics, traversal: &D, parallel: bool, start: f64 ) -> TraversalStatisticswhere E: TElement, D: DomTraversal<E>,

Generate complete traversal statistics.

The traversal time is computed given the start time in seconds.

Trait Implementations

impl Default for TraversalStatistics

fn default() -> TraversalStatistics

Returns the “default value” for a type.

impl Display for TraversalStatistics

Format the statistics in a way that the performance test harness understands. See https://bugzilla.mozilla.org/show_bug.cgi?id=1331856#c2

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
