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

I just haven't looked into the function body at all :-) I think that the best way to format it would probably be
fn parse_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
