Method sync

crates/commitlog/src/lib.rs:272–278

Sync all OS-buffered writes to disk. Note that this does **not** write outstanding records to disk. Use [`Self::flush_and_sync`] or call [`Self::flush`] prior to this method to ensure all data is on disk. Returns the maximum transaction offset which is considered durable after this method returns successfully. The offset is `None` if the log hasn't been flushed to disk yet. # Panics This metho
