source§impl Checkpointer
impl Checkpointer
pub fn new(data_dir: &Path) -> Checkpointer
pub fn view(&self) -> Arc<CheckpointsView>
sourcepub fn maybe_upgrade(
&mut self,
path: &Path,
fresh: FileFingerprint,
fingerprinter: &Fingerprinter,
fingerprint_buffer: &mut Vec<u8>,
)
pub fn maybe_upgrade( &mut self, path: &Path, fresh: FileFingerprint, fingerprinter: &Fingerprinter, fingerprint_buffer: &mut Vec<u8>, )
Scan through a given list of fresh fingerprints to see if any match an existing legacy fingerprint. If so, upgrade the existing fingerprint.
sourcepub fn write_checkpoints(&self) -> Result<usize, Error>
pub fn write_checkpoints(&self) -> Result<usize, Error>
Persist the current checkpoints state to disk, making our best effort to do so in an atomic way that allow for recovering the previous state in the event of a crash.
sourcepub fn read_checkpoints(&mut self, ignore_before: Option<DateTime<Utc>>)
pub fn read_checkpoints(&mut self, ignore_before: Option<DateTime<Utc>>)
Read persisted checkpoints from disk, preferring the new JSON file format but falling back to the legacy system when those files are found instead.
