Function re_build_tools::iter_dir

pub fn iter_dir<'a>(
    path: impl AsRef<Path>,
    extensions: Option<&'a [&'a str]>,
) -> impl Iterator<Item = PathBuf> + 'a

Recursively walks the directory at path in filename order.

If extensions is specified, only files with the right extensions will be iterated. Specified extensions should not include the leading dot, e.g. fbs rather than .fbs.
