History

Fix Rust callbacks dereference msg without a null check (rust.nim:272, 317). CStr::from_ptr(msg) is UB if msg == nullptr. The C++ side guards with msg ? ... : "". The Nim side

appears to always pass a non-null pointer, but soundness across an FFI boundary shouldn't hinge on a producer's discipline — the Rust receiver should null-check. Especially
  since the C ABI signature here is the one downstream consumers will rely on indefinitely.

nim_timer example

This example is a self-contained Nimble project demonstrating how to import nim-ffi and use the .ffiCtor. / .ffi. abstraction.

Usage

Change into the example directory:
```
cd examples/nim_timer
```
Install the local ffi dependency:
```
nimble install -y ../..
```
Build the example library:
```
nimble build
```

Generate bindings:

nimble genbindings_rust
nimble genbindings_cpp

Rust example clients

The Rust client lives in examples/nim_timer/rust_client.

Run the sync example:

cd examples/nim_timer/rust_client
cargo run --bin rust_client

Run the Tokio example:

cd examples/nim_timer/rust_client
cargo run --bin tokio_client

C++ example

The generated C++ example lives in examples/nim_timer/cpp_bindings.

Build and run it with:

cd examples/nim_timer/cpp_bindings
cmake -S . -B build
cmake --build build
./build/example
