  # You are welcome to add new usages and entries to this list, and add the OWNERS of this

  # reach out ahead of time with to be sure your usage sounds OK.

  # It is recommended that you read https://docs.rs/cxx first to understand how cxx works, and to
  # understand what cxx does (and does not) do. All C++ code is still "unsafe" from the Rust
  # perspective; cxx just helps with building the Rust side of the FFI layer safely.
