1. class (Show BackendKey backend, Read BackendKey backend, Eq BackendKey backend, Ord BackendKey backend, PersistCore backend, PersistField BackendKey backend, ToJSON BackendKey backend, FromJSON BackendKey backend) => PersistStoreRead backend

   classy-prelude-yesod	ClassyPrelude.Yesod

   No documentation available.

2. class PersistStoreRead backend => PersistUniqueRead backend

   classy-prelude-yesod	ClassyPrelude.Yesod

   Queries against Unique keys (other than the id Key). Please read the general Persistent documentation to learn how to create Unique keys. Using this with an Entity without a Unique key leads to undefined behavior. A few of these functions require a single Unique, so using an Entity with multiple Uniques is also undefined. In these cases persistent's goal is to throw an exception as soon as possible, but persistent is still transitioning to that. SQL backends automatically create uniqueness constraints, but for MongoDB you must manually place a unique index on a field to have a uniqueness constraint.

3. class YesodBreadcrumbs site

   classy-prelude-yesod	ClassyPrelude.Yesod

   A type-safe, concise method of creating breadcrumbs for pages. For each resource, you declare the title of the page and the parent resource (if present).

4. alreadyExistsErrorType :: IOErrorType

   classy-prelude-yesod	ClassyPrelude.Yesod

   I/O error where the operation failed because one of its arguments already exists.

5. alreadyExpired :: MonadHandler m => m ()

   classy-prelude-yesod	ClassyPrelude.Yesod

   Set an Expires header in the past, meaning this content should not be cached.

6. alreadyInUseErrorType :: IOErrorType

   classy-prelude-yesod	ClassyPrelude.Yesod

   I/O error where the operation failed because one of its arguments is a single-use resource, which is already being used.

7. breadcrumb :: YesodBreadcrumbs site => Route site -> HandlerFor site (Text, Maybe (Route site))

   classy-prelude-yesod	ClassyPrelude.Yesod

   Returns the title and the parent resource, if available. If you return a Nothing, then this is considered a top-level page.

8. breadcrumbs :: (YesodBreadcrumbs site, Show (Route site), Eq (Route site)) => HandlerFor site (Text, [(Route site, Text)])

   classy-prelude-yesod	ClassyPrelude.Yesod

   Gets the title of the current page and the hierarchy of parent pages, along with their respective titles.

9. hIsReadable :: MonadIO m => Handle -> m Bool

   classy-prelude-yesod	ClassyPrelude.Yesod

   Lifted version of hIsReadable

10. hReady :: MonadIO m => Handle -> m Bool

    classy-prelude-yesod	ClassyPrelude.Yesod

    Lifted version of hReady
