Extends the native Rust marshalling to sequences and optionals (the Rust
counterpart of the cpp_native increment): a field maps to Vec<T> / Option<T>,
the repr(C) mirror gains the matching `{ ptr, len }` / `{ present, value }`
fields, and `to_c` now returns a holder owning the CStrings + C-array backing
(Vec/CString live on the heap, so the C struct's raw pointers survive the move
and the call). `from_c` reads seq/Option back out via slice + present-flag.
Unblocks the timer's complex (seq-of-structs / seq-of-strings / two optionals)
and schedule (three struct params). Verified end-to-end — the demo round-trips
typed ComplexResponse / ScheduleResult.

Rust bindings — native (generated)
Generated native (zero-serialization) Rust crate for the timer library — the
Rust counterpart of c_bindings / go_bindings / cpp_native_bindings, and the
native sibling of the CBOR crate in ../rust_bindings.
| File | Description |
|---|---|
src/ffi.rs |
#[repr(C)] POD mirrors + extern "C" native entry points. |
src/types.rs |
Idiomatic structs + to_c/from_c (a holder owns the CStrings for the call). |
src/api.rs |
<Lib>Node — methods marshal typed args in / read typed struct returns out; blocking via std::sync::mpsc. No CBOR. |
examples/demo.rs |
A small consumer. |
let node = MyTimerNode::new(TimerConfig { name: "my-app".into() })?;
println!("{}", node.version()?);
let r = node.echo(EchoRequest { message: "hello".into(), delay_ms: 5 })?; // -> EchoResponse
Regenerate with nimble genbindings_rust_native.
Status
Requests are fully supported: scalar / string / bool / float / nested struct
and now sequences (Vec) and optionals (Option) — create, version, echo,
complex, schedule all generate and round-trip typed values. to_c returns a
holder that owns the CStrings and C-array backing (heap, so the C struct's raw
pointers stay valid across the move and for the call).
Still to come: native typed events and the native-bare / _cbor reconciliation.
Linking is left to the consumer (-L <dir> -l my_timer + rpath, as in
examples/demo.rs); a build.rs that compiles the dylib can be added later.
