Expose structured access to JsonReply error code and supported_versions in FFI #1271
Closed as not planned
Description
JsonReply / WellKnownError are currently exposed as JSON strings only. Integrators must parse strings to discover the code and supported_versions.
Todo:
- Expose WellKnownError as a typed FFI record (code + supported_versions).
- Expose JsonReply with typed accessors rather than string parsing.
- Add binding tests for code matching (Unavailable, VersionUnsupported, etc.).
- Ensure error serialization still round‑trips across languages.
