runtime call support #59

Open gilescope opened 1 year ago

We can get the rpc methods like this:

curl -sS -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "rpc_methods"}' http://localhost:9933/

I don't think there's a way in polkadot at the moment to get the same list of method strings that one can feed into the state_call rpc method. We suggest that people do state call runtime functions rather than doing custom rpc calls because you can add them via a runtime upgrade without needing to update the node. But they are not as discoverable at the moment.

E.g. state_call "Metadata_metadata" 0x does the equivilent of the rpc metadata call, but discovering this at the moment is not easy.

I would need to look into that. Keep in mind that subwasm only works off the runtime. If there is a call that does not require storage and returns those functions, there should be an option. subwasm does not call any jsonrpc endpoint (besides the convenience to fetch the runtime from a node).

The information should be only in the runtime. I had my doubts but now I do think subwasm is the right place.
