History

fix C++ "async" methods spawn a thread per call that then blocks on a condvar (cpp.nim:362–377). std::async(std::launch::async, ...) forces a fresh thread, and the body runs

the blocking ffi_call_ which waits on a condvar with the user's timeout (default 30s). Under load this is a thread-explosion factory, and the name "async" is misleading — the
  Rust side has real async via tokio oneshot, but the C++ side has fake async. If true async isn't reachable in C++ without coroutines, fine, but at least pool the threads or
  document this is just a convenience wrapper.

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
