Exact lookup

1. type SqlBackendCanRead backend = (BackendCompatible SqlBackend backend, PersistQueryRead backend, PersistStoreRead backend, PersistUniqueRead backend)

   persistent	Database.Persist.Sql.Types.Internal

   A constraint synonym which witnesses that a backend is SQL and can run read queries.

2. newtype SqlReadBackend

   persistent	Database.Persist.Sql.Types.Internal

   An SQL backend which can only handle read queries The constructor was exposed in 2.10.0.

3. SqlReadBackend :: SqlBackend -> SqlReadBackend

   persistent	Database.Persist.Sql.Types.Internal

   No documentation available.

4. type SqlReadT (m :: Type -> Type) a = forall backend . SqlBackendCanRead backend => ReaderT backend m a

   persistent	Database.Persist.Sql.Types.Internal

   Like SqlPersistT but compatible with any SQL backend which can handle read queries.

5. unSqlReadBackend :: SqlReadBackend -> SqlBackend

   persistent	Database.Persist.Sql.Types.Internal

   No documentation available.

6. RepeatableRead :: IsolationLevel

   persistent	Database.Persist.SqlBackend.Internal.IsolationLevel

   No documentation available.

7. runReader :: Reader a -> Text -> Either Text a

   http-api-data	Web.Internal.HttpApiData

   Run Reader as HTTP API data parser.

8. data ThreadId

   lifted-base	Control.Concurrent.Lifted

   A ThreadId is an abstract type representing a handle to a thread. ThreadId is an instance of Eq, Ord and Show, where the Ord instance implements an arbitrary total ordering over ThreadIds. The Show instance lets you convert an arbitrary-valued ThreadId to string form; showing a ThreadId value is occasionally useful when debugging or diagnosing the behaviour of a concurrent program. Note: in GHC, if you have a ThreadId, you essentially have a pointer to the thread itself. This means the thread itself can't be garbage collected until you drop the ThreadId. This misfeature would be difficult to correct while continuing to support threadStatus.

9. isCurrentThreadBound :: MonadBase IO m => m Bool

   lifted-base	Control.Concurrent.Lifted

   Generalized version of isCurrentThreadBound.

10. killThread :: MonadBase IO m => ThreadId -> m ()

    lifted-base	Control.Concurrent.Lifted

    Generalized version of killThread.
