Adds native (zero-CBOR) event support to the Rust generator, mirroring the cpp_native / Go event path: a per-event `add_<wire>_listener` registrar takes a closure, boxes it, and registers it through the bare `<lib>_add_event_listener` (native) entry point. The extern "C" trampoline reads the payload as the raw C-POD struct and hands the consumer a borrowed idiomatic value via from_c — no serialization on the hot path. The node owns the boxed closures in a Mutex<HashMap<id, Box<dyn Any>>> keyed by listener id so they outlive the call, and `remove_event_listener` drops them and calls the bare remove entry point. Event externs are only emitted when the library declares events, so event-free crates stay minimal. Verified end-to-end: the demo registers a listener, echo fires on_echo_fired inline, the typed EchoEvent reaches the closure, and removal returns true.

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).
Native typed events are supported too: add_<event>_listener takes a closure
receiving the payload as a borrowed idiomatic struct (the trampoline reads the
raw C-POD directly — no CBOR), the handle goes through remove_event_listener,
and the node owns the boxed closures for their lifetime.
Still to come: the native-bare / _cbor filename 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.
