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-ffi

Allows exposing Nim projects to other languages

Example

examples/nim_timer is now a self-contained Nimble project that imports nim-ffi directly. Use cd examples/nim_timer && nimble install -y ../.. && nimble build to compile the example.
