Function proto_build_tools::build_protos

pub fn build_protos(out_dir: &PathBuf, proto_paths: &[PathBuf])

Builds a set of Rust protos based on the provided proto files. The individual protos will be dumped into out_dir (will be created if needed), along with a file that wraps them out_dir/generated.rs. The wrapper file can then be included using a pattern like:

pub mod protos {
   // Suppose the `out_dir` supplied to `build_protos` was
   // format!("{}/my_crate_protos", env!("OUT_DIR"))
   include!(concat!(env!("OUT_DIR"), "/my_crate_protos/generated.rs"));
}
// Protos are available at protos::proto_file_name.
