CorruptionPolicy

nodedb_lite::storage::corruption

Enum CorruptionPolicy 

Source 
pub enum CorruptionPolicy {
    FailClosed,
    DiscardStoreAndRecreate,
}
Expand description

How open reacts to a corruption-class fault in the store it was asked to open.

Variants§

§

FailClosed

Report the corruption and leave every byte where it is. The default.

Open returns a corruption-class error the caller can match on (ErrorDetails::SegmentCorrupted). Nothing is renamed, deleted, or created, so the store is in the same state after the failed open as before it — available for pagedb-fsck, for a byte-for-byte backup, or for a later open under a different policy.

§

DiscardStoreAndRecreate

Rename the damaged store aside and continue against a fresh, empty one.

The old store is moved to {path}.corrupt.{unix_secs} and never deleted, but a caller opting into this is choosing to start empty: the database that comes back has none of the previous data in it, and any writes it accepts diverge from the copy set aside. Only meaningful when the caller has another source of truth to refill from.
