# Documentation

data AsServerT (m :: Type -> Type) Source #

A type that specifies that an API record contains a server implementation.

#### Instances

Instances details

GenericMode (AsServerT m :: Type) Source # |
Instance details Defined in Servant.Server.Internal
type (AsServerT m :: Type) :- api Source # |
Instance details Defined in Servant.Server.Internal type (AsServerT m :: Type) :- api = ServerT api m

type AsServer = AsServerT Handler Source #

genericServe :: (HasServer (ToServantApi routes) ('[] :: [Type]), GenericServant routes AsServer, Server (ToServantApi routes) ~ ToServant routes AsServer) => routes AsServer -> Application Source #

Transform a record of routes into a WAI `Application`.

genericServeT Source #

Arguments

:: (GenericServant routes (AsServerT m), GenericServant routes AsApi, HasServer (ToServantApi routes) ('[] :: [Type]), ServerT (ToServantApi routes) m ~ ToServant routes (AsServerT m)) |
=> (forall a. m a -> Handler a) | `hoistServer` argument to come back to `Handler`
-> routes (AsServerT m) | your record full of request handlers
-> Application |

Transform a record of routes with custom monad into a WAI `Application`, by providing a transformation to bring each handler back in the `Handler` monad.

genericServeTWithContext Source #

Arguments

:: forall routes m (ctx :: [Type]). (GenericServant routes (AsServerT m), GenericServant routes AsApi, HasServer (ToServantApi routes) ctx, HasContextEntry (ctx .++ DefaultErrorFormatters) ErrorFormatters, ServerT (ToServantApi routes) m ~ ToServant routes (AsServerT m)) |
=> (forall a. m a -> Handler a) | `hoistServer` argument to come back to `Handler`
-> routes (AsServerT m) | your record full of request handlers
-> Context ctx | the `Context` to serve the application with
-> Application |

Transform a record of routes with custom monad into a WAI `Application`, while using the given `Context` to serve the application (contexts are typically used by auth-related combinators in servant, e.g to hold auth checks) and the given transformation to map all the handlers back to the `Handler` monad.

genericServer :: GenericServant routes AsServer => routes AsServer -> ToServant routes AsServer Source #

Transform a record of endpoints into a `Server`.

genericServerT :: forall routes (m :: Type -> Type). GenericServant routes (AsServerT m) => routes (AsServerT m) -> ToServant routes (AsServerT m) Source #

Transform a record of endpoints into a ``ServerT` m`.

You can see an example usage of this function in the Servant Cookbook.
