A transpiler from ROS2's message types to Rust's types.
This library is used by [cargo-ament-build](https://github.com/tier4/cargo-ament-build) internally.
```rust
use safe_drive_msg;
use std::path::Path;
let dependencies = ["std_msgs", "std_srvs"];
safe_drive_msg::depends(&Path::new("/tmp/output_dir"), &dependencies, safe_drive_msg::SafeDrive::Version("0.2"));
```
This does not support C/C++ like preprocessor.
