zenoh-flat

zenoh-flat exposes two complementary API tiers from one flat Rust crate surface.

API split

• base contains the low-level Zenoh-facing API: z_* functions plus the supporting enums and value types needed to drive them directly.
• expanded contains wrapper data types, impl Into<_>-style ergonomic entry points, and one-hop expansion helpers that turn native Zenoh values into binding-friendly structs.

Internally, the source tree is organized as src/base/ and src/expanded/, but the crate continues to re-export everything from zenoh_flat::*.

Why the split exists

• Languages with cheap native calls can stay on the base tier and pull fields through fine-grained z_* accessors.
• Languages with expensive native calls can use the expanded tier, where generated bindings convert wrapper structs to and from native Zenoh values in fewer FFI hops.

That makes the same annotated Rust source usable for both C-style low-level bindings and higher-level generated bindings such as JNI/Kotlin.
