Serialization framework with some interesting numbers: 10-20x faster on nested objects than json/protobuf.

  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.

I'm wondering how do you share you shared types between languages if there's no schema ?

I am skeptical that it's possible to make this work in the long run.

I get your concern — for one or two languages, skipping an IDL can work well and keeps things simple.

But once you’re dealing with three or more languages, I agree an IDL becomes valuable as a single source of truth. That’s work we’ve started: adding optional IDL support so teams can generate data structures in each language from one shared definition.
