Struct UpdateIntegrityValidator 

pub struct UpdateIntegrityValidator<'a, T, M, A = AccessControlList>
where
    T: TableSchema,
    M: MemoryProvider,
    A: AccessControl,
{ /* private fields */ }

Unlike super::InsertIntegrityValidator, this validator allows the primary key to remain unchanged during an update.
