   persistent	Database.Persist.Sql

8. class HasPersistBackend backend

   persistent	Database.Persist.Sql.Types.Internal

   Class which allows the plucking of a BaseBackend backend from some larger type. For example, instance HasPersistBackend (SqlReadBackend, Int) where type BaseBackend (SqlReadBackend, Int) = SqlBackend persistBackend = unSqlReadBackend . fst

9. class HasPersistBackend backend => IsPersistBackend backend

   persistent	Database.Persist.Sql.Types.Internal

   Class which witnesses that backend is essentially the same as BaseBackend backend. That is, they're isomorphic and backend is just some wrapper over BaseBackend backend.

10. mkPersistBackend :: IsPersistBackend backend => BaseBackend backend -> backend

    persistent	Database.Persist.Sql.Types.Internal

    This function is how we actually construct and tag a backend as having read or write capabilities. It should be used carefully and only when actually constructing a backend. Careless use allows us to accidentally run a write query against a read-only database.
