Looks like there is more here than meets the eye. Maybe best to leave this for a Rust dev who knows more than I. https://github.com/rust-lang/rust-clippy/issues/9111

@austinvazquez Instead of "src/ttrpc.proto", ["src/ttrpc.proto"] would be right. Would you like to reopen it or I will create a new pr later. Thanks anyway

Thanks @Tim-Zhang; I'll give it a try.
