Network.JsonRpc.TinyClient
Description
Tiny JSON-RPC 2.0 client. Functions for implementing the client side of JSON-RPC 2.0. See http://www.jsonrpc.org/specification.
If you have monad with MonadIO, MonadThrow and MonadReader instances,
it can be used as base for JSON-RPC calls.
Example:
newtype MyMonad a = ... instance JsonRpc MyMonad foo :: Mymonad Text foo = remote "foo"
Arguments of function are stored into params request array.
Example:
myMethod :: JsonRpc m => Int -> Bool -> m String myMethod = remote "myMethod"
Synopsis
- class JsonRpcM m => JsonRpc m where
- remote :: Remote m a => MethodName -> a
- type MethodName = Text
- data JsonRpcClient
- defaultSettings :: MonadIO m => String -> m JsonRpcClient
- jsonRpcServer :: Lens' JsonRpcClient String
- jsonRpcManager :: Lens' JsonRpcClient Manager
- data JsonRpcException
- data RpcError = RpcError {}
The JSON-RPC remote call monad
class JsonRpcM m => JsonRpc m where Source #
JSON-RPC call monad.
