Hipsql.Monad
Description
This module provides a low-dependency integration point for
supporting hipsql interop in your own Monad.
In practice, you generally want to define an instance for
MonadHipsqlAdapter and use the orphan instance for MonadHipsql provided
by importing Adapter from hipsql-server. This way,
you can optionally depend on hipsql-server only when you need to
but can always depend on hipsql-monad, the latter of which would
not cause you to transitively depend on any additional packages.
Synopsis
- class MonadHipsql m where
- hipsql :: HasCallStack => m ()
- class MonadHipsqlAdapter m where
- hipsqlAcquireLibPQ :: (Connection -> IO a) -> m a
Documentation
class MonadHipsql m where Source #
Type class for starting a hipsql session in a Monad m.
N.B. You generally do not want to define this instance on your own. See the haddock at the top of this module.
class MonadHipsqlAdapter m where Source #
Convenience type class used for deriving instances of MonadHipsql.
See the haddock at the top of this module for an explanation.
