Rollbacks the migrations of a group to a given version.
Before issuing a rollback, all migrations are validated.

Verifies if the provided migrations are a superset of the migrations within the database by verification their checksums.

pub fn new(backend: B) -> Self[src]
Creates a new instance from a given backend.
pub fn backend_mut(&mut self) -> &mut B[src]
