Enum CheckpointKey 

pub enum CheckpointKey {
    PoolOpened,
}

Identifies which on-chain event watcher a persisted scan checkpoint belongs to (#1092). Every variant maps to a stable string key in the single watcher_checkpoint_v1 table, so one concrete store holds every watcher’s high-water mark (redb forbids two Database handles to one file).

The as_str literals are on-disk identifiers: renaming one silently forfeits that watcher’s resume (its next boot re-scans from the configured floor instead of the stored block), so each one stays fixed for as long as the on-disk format does.

Variants

PoolOpened

Redemption watcher PoolOpened high-water block.
