Description

This module is a utility for `servant-client-core` backend writers. It contains all the functionality from `servant-client-core` that should be re-exported.

# HasClient

class RunClient m => HasClient (m :: Type -> Type) api where #

This class lets us define how each API combinator influences the creation of an HTTP request.

Unless you are writing a new backend for `servant-client-core` or new combinators that you want to support client-generation, you can ignore this class.

foldMapUnion :: forall c a (as :: [Type]). All c as => Proxy c -> (forall x. c x => x -> a) -> Union as -> a #

Convenience function to apply a function to an unknown union element using a type class. All elements of the union must have instances in the type class, and the function is applied unconditionally.

See also: `matchUnion`.

matchUnion :: forall a (as :: [Type]). IsMember a as => Union as -> Maybe a #

Convenience function to extract a union element using `cast`, ie. return the value if the selected type happens to be the actual type of the union in this value, or `Nothing` otherwise.

See also: `foldMapUnion`.

type (AsClientT m :: Type) :- api # |
Instance details Defined in Servant.Client.Core.HasClient type (AsClientT m :: Type) :- api = Client m api

(//) :: a -> (a -> b) -> b infixl 1 #

Helper to make code using records of clients more readable.

Can be mixed with (/:) for supplying arguments.

Example:

    type Api = NamedRoutes RootApi

    data RootApi mode = RootApi
      { subApi :: mode :- NamedRoutes SubApi
      , …
      } deriving Generic

    data SubApi mode = SubApi
      { endpoint :: mode :- Get '[JSON] Person
      , …
      } deriving Generic

    api :: Proxy API
    api = Proxy

    rootClient :: RootApi (AsClientT ClientM)
    rootClient = client api

    endpointClient :: ClientM Person
    endpointClient = client // subApi // endpoint

(/:) :: (a -> b -> c) -> b -> a -> c infixl 2 #

Convenience function for supplying arguments to client functions when working with records of clients.

Intended to be used in conjunction with `(//)`.

Example:

    type Api = NamedRoutes RootApi

    data RootApi mode = RootApi
      { subApi :: mode :- Capture "token" String :> NamedRoutes SubApi
      , hello :: mode :- Capture "name" String :> Get '[JSON] String
      , …
      } deriving Generic

    data SubApi mode = SubApi
      { endpoint :: mode :- Get '[JSON] Person
      , …
      } deriving Generic

    api :: Proxy API
    api = Proxy

    rootClient :: RootApi (AsClientT ClientM)
    rootClient = client api

    hello :: String -> ClientM String
    hello name = rootClient // hello /: name

    endpointClient :: ClientM Person
    endpointClient = client // subApi /: "foobar123" // endpoint
