Enum Defect 

#[non_exhaustive]
pub enum Defect {
    NoTransactions,
    LossyBytes,
    UnclassifiedErrors,
    NoMigrationLedger,
}

One way for a wrapped backend to be wrong, for the known-bad controls.

Variants (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.

NoTransactions

begin returns a transaction whose statements run at once and whose rollback and drop do nothing.

LossyBytes

A byte parameter is cut to its first byte.

UnclassifiedErrors

Every error comes back as RelError::Backend.

NoMigrationLedger

As a migrator (Migrates): no ledger, no checksum, no transaction; every migration runs again each time it is asked. Used by migrate_conformance.
