For each request type, define the following:
|
|
|
|
1. RpcRequest "To" method [message.go], which does basic validation and conversion to "Args" type via json.Decoder()
|
|
2. json.Decoder() calls "UnmarshalON" defined on each "Args" struct
|
|
3. EthereumApi method, taking the "Args" type and replying with an interface to be marshalled to ON
