A segment represents a pruning of some portion of the data.

Segments are called from Pruner with the following lifecycle:

1. Call Segment::prune with delete_limit of PruneInput.
2. If Segment::prune returned a Some in checkpoint of SegmentOutput, call Segment::save_checkpoint.
3. Subtract pruned of SegmentOutput from delete_limit of next PruneInput.

Required Methods

fn segment(&self) -> PruneSegment

Segment of data that’s pruned.

fn mode(&self) -> Option<PruneMode>

Prune mode with which the segment was initialized.

fn purpose(&self) -> PrunePurpose

Purpose of the segment.

fn prune( &self, provider: &Provider, input: PruneInput, ) -> Result<SegmentOutput, PrunerError>

Prune data for Self::segment using the provided input.

Provided Methods

fn save_checkpoint( &self, provider: &Provider, checkpoint: PruneCheckpoint, ) -> ProviderResult<()>

where Provider: PruneCheckpointWriter,

Save checkpoint for Self::segment to the database.
