 - Encoding of `CandidFunctionProtocol` is not supported as there is no easy way to infer the `CandidTypes` used in the arguments and results of the function. This means that the automatic code generation will fail when calling a canister method that expects another function as input.
 - Encoding of `CandidServiceProtocol` is not supported because functions can not be encoded. 
 - Encoding of optional `Structs` can not infer the members of the struct. These are encoded as `opt empty` which should be accepted by all canisters according to Candid specifications.
