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.

These binary protocols generally also try to keep the data size small. Protobuf is essentially compressing its integers (varint or zigzag encoding), for example.

It'd be helpful to see a plot of serialization costs vs data size. If you only display serialization TPS, you're always going to lose to the "do nothing" option of just writing your C structs directly to the wire, which is essentially zero cost.

It appears there are two schema compatibility modes and no guarantee of minor version binary compatibility.
