I'm wondering how do you share you shared types between languages if there's no schema ?
replies(4):
Technical approach: compile-time codegen (no reflection), compact binary protocol with meta-packing, little-endian layout optimized for modern CPUs.
Unique features that other fast serializers don't have:
- Cross-language without IDL files (Rust ↔ Python/Java/Go)
- Trait object serialization (Box<dyn Trait>)
- Automatic circular reference handling
- Schema evolution without coordination
Happy to discuss design trade-offs.
Benchmarks: https://fory.apache.org/docs/benchmarks/rustOtherwise, the schema seems to be derived from the class being serialized for typed languages, or otherwise annotated in code. The serializer and deserializer code must be manually written to be compatible instead of both sides being codegen'd to match from a schema file. He's the example I found for python: https://fory.apache.org/docs/docs/guide/python_serialization...
When running in compatible mode, Fory automatically derives a compact schema from those definitions at runtime time and sends it along to peers for the first time serialization. That way, both sides know the structure without needing a separate schema file.
The idea is to make cross‑language exchange work out‑of‑the‑box, while still allowing teams to add an explicit IDL later if they want a single source of truth.
