PoolTruncation

pepper_sync::sync::truncate

Enum PoolTruncation 

Source 
pub enum PoolTruncation {
    ToCheckpoint {
        checkpoint: BlockHeight,
    },
    Untouched,
    RequiresRescan {
        newest_checkpoint: BlockHeight,
    },
}
Expand description

The correct truncation outcome for one shard tree, carrying the evidence that justifies it.

Variants§

§

ToCheckpoint

The tree holds this checkpoint at the target height: roll back to it.

Fields

§checkpoint: BlockHeight

The checkpoint found at the target height.

§

Untouched

The tree records no chain state above the target height (its newest checkpoint, if any, is at or below it): leave it untouched.

§

RequiresRescan

The tree holds state above the target height but no checkpoint at it: rollback is impossible, and only a full clear and rescan restores integrity.

Fields

§newest_checkpoint: BlockHeight

The newest checkpoint above the target that condemned the tree.
