There was a problem hiding this comment.
why not
fnparse_failure_msg(tok:&Token) -> String{iflet token::Eof = tok.kind{return"unexpected end of macro invocation".to_string();}format!("no rules expected the token `{}`", pprust::token_to_string(tok))}ContributorAuthor

I just haven't looked into the function body at all :-) I think that the best way to format it would probably be
fnparse_failure_msg(tok:&Token) -> String{match tok.kind{
token::Eof => "unexpected end of macro invocation".to_string(),
_ => format!("no rules expected the token `{}`", pprust::token_to_string(tok)),}}Not a fan of if let with an else case
