Member Function Documentation

reconcilePathMeasurement()

bool donner::svg::RendererDrawBudget::reconcilePathMeasurement ( const PathMeasurementReservation & reservation, std::size_t actualWorkUnits, bool completed )

inlinenodiscard

Reconciles an exclusive path-measurement reservation to work actually consumed.

An incomplete query consumes its reported work and rejects the aggregate budget.

reservePathMeasurement()

std::optional< PathMeasurementReservation > donner::svg::RendererDrawBudget::reservePathMeasurement ( )

inlinenodiscard

Reserves all remaining path-measurement work before a bounded query starts.

The caller must pass the returned maximum to the query, then call reconcilePathMeasurement with the query's actual work and completion outcome.
