(&mut self, lsn: u64)

    /// The WAL can be safely truncated up to this LSN after
    /// all engines have flushed their dirty pages.
    pub fn complete_checkpoint(&mut self, lsn: u64) {
        self.checkpoint_lsn = lsn;
        self.checkpoint_count += 1;
        info!(lsn, count = self.checkpoint_count, "checkpoint completed");
    }

    /// LSN of the last completed checkpoint.
