The monad for RPC clients
The TH functions to construct RPC client functions from RPC server ones

Description

Creates a client out of list of RPC server components.

Synopsis

newtype RpcClientMonad a = RpcClientMonad {
- runRpcClientMonad :: ReaderT Client ResultG a
}
runRpcClient :: (MonadBase IO m, MonadError GanetiException m) => RpcClientMonad a -> Client -> m a
callMethod :: (JSON r, JSON args) => String -> args -> RpcClientMonad r
mkRpcCall :: Name -> Q [Dec]
mkRpcCalls :: [Name] -> Q [Dec]

The monad for RPC clients

newtype RpcClientMonad a Source #

The monad for all client RPC functions. Given a client value, it runs the RPC call in IO and either retrieves the result or the error.

The TH functions to construct RPC client functions from RPC server ones

runRpcClient :: (MonadBase IO m, MonadError GanetiException m) => RpcClientMonad a -> Client -> m a Source #

Given a client run a given client RPC action.

callMethod :: (JSON r, JSON args) => String -> args -> RpcClientMonad r Source #

mkRpcCall :: Name -> Q [Dec] Source #

Given a server RPC function (such as from WConfd.Core), creates the corresponding client function. The monad of the result type of the given function is replaced by RpcClientMonad and the new function is implemented to issue a RPC call to the server.

mkRpcCalls :: [Name] -> Q [Dec] Source #
