The syn crate does not preserve span information while parsing the Rust code, so we no longer have access to accurate information about where each attribute begins and ends. This adds a simple heuristic: we simply search for html_root_url in the source code and use that line in the error message.
The error message from the syn crate is quite verbose. Simply recompiling the crate with "cargo build" will give better and more familiar output to the user.
