History

fix(codegen): Rust bindings target the *_cbor request exports

The Rust wrapper speaks CBOR, but after the native/CBOR split it still declared
and called the bare `<name>` request symbols — which are now the *native*
(typed-args) entry points, so every Rust request hit the wrong ABI (struct/ptr
mismatch). This is the Rust counterpart of the C++ fix (914c70a), which was
missed at the time. Point the ffi.rs externs and the api.rs ctor/method calls at
`<name>_cbor`; the destructor has no CBOR variant and the event registration is
unchanged here.

Verified at runtime: the rust_client now creates a context and round-trips
version / echo / schedule over CBOR.

Rust Bindings for nim-timer

Purpose

This folder contains auto-generated Rust bindings (the my_timer crate) for the my_timer Nim library. It is generated from ../timer.nim and provides:

src/lib.rs: Main library exposing high-level Rust types and the MyTimerCtx API
src/api.rs: High-level async/sync wrapper around the FFI
src/ffi.rs: Raw extern "C" declarations for the Nim library
src/types.rs: Serializable Rust types matching the Nim FFI types
build.rs: Build script that compiles the Nim library to libmy_timer.dylib (or .so/.dll)
Cargo.toml: Package manifest with serde and serde_json dependencies

How It's Generated

Generate or regenerate these bindings by running from the parent directory:

cd examples/timer
nimble genbindings_rust

This command:

Invokes the Nim compiler with -d:targetLang:rust flag
Triggers genBindings("examples/timer/rust_bindings", "../timer.nim") in timer.nim
Creates/updates the generated binding files

Using as a Dependency

The rust_client example consumes this crate:

[dependencies]
my_timer = { path = "../rust_bindings" }

Do Not Edit

The generated files in this folder are overwritten each time nimble genbindings_rust runs. Any manual changes will be lost.
