Errors that can occur when interacting with an authenticated database.

Variants

DataCorrupted(&'static str)

Merkle(Error<F>)

Metadata(Error)

Journal(Error)

Runtime(Error)

OperationPruned(Location<F>)

KeyNotFound

The requested key was not found in the snapshot.

KeyExists

The key exists in the db, so we cannot prove its exclusion.

UnexpectedData(Location<F>)

LocationOutOfBounds(Location<F>, Location<F>)

PruneBeyondMinRequired(Location<F>, Location<F>)

StaleBatch

The batch was created from a different database state than the current one.

Fields

db_size: u64

batch_db_size: u64

batch_base_size: u64

FloorRegressed(Location<F>, Location<F>)

The batch’s inactivity floor is lower than the database’s current floor.

FloorBeyondSize(Location<F>, Location<F>)

The batch’s inactivity floor exceeds its own commit operation’s location. The floor must not sit past the commit, since a subsequent prune(floor) would then remove the last readable commit from the journal.

HistoricalFloorPruned(Location<F>)

The inactivity floor that governed the requested historical_size is not retrievable from the journal, so the wrapper cannot derive the inactive_peaks count needed to construct a proof matching the historical root.

Historical proofs require historical_size to be a commit-boundary: the operation at historical_size - 1 must itself be a commit op declaring the governing floor. This error fires when the caller passes a non-commit-boundary size, or when pruning has removed the commit that would have governed the size.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
