Implementations§

Source§

impl GraphStatistics

Source

pub fn advanced_statistics_freshness( &self, current_commit_epoch: u64, ) -> AdvancedStatisticsFreshness

Classifies only advanced statistics; basic counts may be newer than this snapshot.

Source

pub fn advanced_statistics_commit_lag(&self, current_commit_epoch: u64) -> u64

Returns the observable lag without underflowing on an invalid future snapshot epoch.
