Suggest a fix/enhancement

Start with the swagger-codegen CLI generate command and the Rust language configuration loading path, using the provided all.yaml URL and -l rust invocation to reproduce the exception. Done means the command no longer reports that it cannot load the rust config class and reaches Rust client generation.
