Name of called method.

JSON-RPC server URI

class (MonadIO m, MonadThrow m, MonadReader Config m) => Remote m a | a -> m #

Typeclass for JSON-RPC monad base.

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 Remote MyMonad (Mymonad a)

  foo :: Int -> Bool -> Mymonad Text
  foo = remote "foo"

Instances

FromJSON a => Remote Web3 (Web3 a) #
Instance details Defined in Network.Ethereum.Web3.Provider Methods remote_ :: ([Value] -> Web3 ByteString) -> Web3 a
(ToJSON a, Remote m b) => Remote m (a -> b) #
Instance details Defined in Network.JsonRpc.TinyClient Methods remote_ :: ([Value] -> m ByteString) -> a -> b

Remote call of JSON-RPC method.

Arguments of function are stored into params request array.

Example:

  myMethod :: Int -> Bool -> m String
  myMethod = remote "myMethod"
