Synopsis

class SiteTrans (t :: * -> *) where
- lift :: MonadSite m => m site a -> m (t site) a
- mapSiteT :: (MonadSite m, MonadSite n, SiteCompatible site site') => (m site a -> n site' b) -> m (t site) a -> n (t site') b

Documentation

class SiteTrans (t :: * -> *) where Source #

The class of site transformations

A site transformation is a wrapper around a Yesod foundation site which augments it with additional functionality.

Methods

lift :: MonadSite m => m site a -> m (t site) a Source #

Lift a Yesod computation to a transformed computation, typically by wrapping the foundation site directly

mapSiteT :: (MonadSite m, MonadSite n, SiteCompatible site site') => (m site a -> n site' b) -> m (t site) a -> n (t site') b Source #

Transform the Yesod computation under a site transformation
