The first non-comment, non-use line in the file is
#[derive(Debug)], which might be where this is coming from?oli-obk commentedon Aug 31, 2017
No, the first item is inside the expansion. We need a macro check. I don't think Rust's lints have any, but clippy has a convenience function in almost every lint. We should probably upstream it. There are so many diagnostics that choke on expansions.
