There was a problem hiding this comment.
Why the format_args instead of just passing &self.inner.inner to field()?

That's better, I forgot field already takes &dyn Debug.

Yes, those also produce the same result: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=dbe3d60846cf29e0f4d51f85c6012bfa |

This removes the method
sys::args::Args::inner_debugon all platforms and implementsDebugforArgsinstead.I believe this creates a more natural API for the different platforms under
sys: export a typeArgs: Debug + Iterator + ...vs.Args: Iterator + ...and with a methodinner_debug.
