Nice! Just a few nits.

Previously, the `Balance`, `Price` and `Weight` were serialized directly into u128 numbers in #238, but polkadot.js could not parse them successfully. Therefore, it is necessary to serialize `Balance`, `Price`, and `Weight` back to String. Unlike before, the serialization conversion of `Balance` and `Price` only occurs at the RPC layer and does not involve the types in the pallet (because the `Weight` is an alias of u128, so we use serde derive directly on the type to complete the serialization conversion).

JSON serialization/deserialization of
i128/u128can only be supported when thearbitrary_precisionfeature enabled.But
arbitrary_precisionnumbers don't work withserde(tag = ..)andserde(flatten)syntax (serde-rs/json#505), as a result, the deserialization of structures injsonrpc-corewill be error.Fortunately, the crate
jsonrpc-coreprovides a workround(paritytech/jsonrpc#521).Although this workround will cause more extra serialization/deserialization work, but I think it's worth it.
