Expand description

Superset of all other errors that can occur. Convenience enum so that users can convert all errors into a single type

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

DatabaseAlreadyOpen

The Database is already open. Cannot acquire lock.

§

InvalidSavepoint

This savepoint is invalid or cannot be created.

Savepoints become invalid when an older savepoint is restored after it was created, and savepoints cannot be created if the transaction is “dirty” (any tables have been opened)

§

RepairAborted

§

PersistentSavepointExists

A persistent savepoint exists

§

EphemeralSavepointExists

An Ephemeral savepoint exists

§

TransactionInProgress

A transaction is still in-progress

§

Corrupted(String)

The Database is corrupted

§

UpgradeRequired(u8)

The database file is in an old file format and must be manually upgraded

§

ValueTooLarge(usize)

The value being inserted exceeds the maximum of 3GiB

§

TableTypeMismatch

Table types didn’t match.

Fields

§table: String
§value: TypeName
§

TableIsMultimap(String)

The table is a multimap table

§

TableIsNotMultimap(String)

The table is not a multimap table

§

TypeDefinitionChanged

Fields

§alignment: usize
§width: Option<usize>
§

TableDoesNotExist(String)

Table name does not match any table in database

§

TableAlreadyOpen(String, &'static Location<'static>)

§

Io(Error)

§

PreviousIo

A previous IO error occurred. The database must be closed and re-opened

§

LockPoisoned(&'static Location<'static>)

§

ReadTransactionStillInUse(ReadTransaction)

The transaction is still referenced by a table or other object
