What a trace’s records add up to.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

frames: u32

The records summed up: the frames kept.

dropped: u64

How many earlier frames’ records were no longer kept.

frame: Spread

How the whole frame’s time spread (frame_us).

update: Spread

How the update’s spread (update_us).

draw: Spread

How the drawing’s spread (draw_us).

paint: Spread

How painting into the window spread (paint_us).

present: Spread

How the backend’s swap and wait spread (present_us).

spans: Vec<SpanSummary>

The spans with the most time in all, most first (ties by name), at most five.

heap: Option<HeapSummary>

The heap’s counts over the records that have them; null where none has (a release build of the tool program, or one opted out).

heap_tags: Vec<TagRow>

What held the heap after the last frame: the snapshot’s first ten rows by tag, the most live bytes first. Empty without a snapshot.

heap_growth: Option<HeapDiff>

What grew and shrank from the snapshot before the run to the one after: the diff, with its first ten rows, the largest change first. Null without snapshots.

file: Option<String>

The trace file written, its absolute path, with --perf-out.

Trait Implementations

impl Clone for PerfSummary

fn clone(&self) -> PerfSummary

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.
