Native Serialization

Native serialization uses a binding-specific wire format and the owning runtime's native type system. It is not one shared cross-language protocol.

When to use native mode

Use native mode for same-runtime traffic that needs language-specific object shapes, migration from a host serializer, or a smaller/faster format without xlang type-mapping constraints. Use xlang mode whenever a different runtime must read the bytes.

Supported runtime families

• Java, including the JVM path used by Scala and Kotlin
• Python
• C++
• Go
• Rust
• Scala
• Kotlin

Each runtime page owns its exact object model, schema rules, configuration, extension APIs, and diagnostics. Native payloads from different runtime families are not interchangeable.
