Matthias Krüger 1a6ed3050f Rollup merge of #103439 - Nilstrieb:help-me-with-my-macro, r=estebank ... Show note where the macro failed to match When feeding the wrong tokens, it used to fail with a very generic error that wasn't very helpful. This change tries to help by noting where specifically the matching went wrong. ```rust macro_rules! uwu { (a a a b) => {}; } uwu! { a a a c } ``` ```diff error: no rules expected the token `c` --> macros.rs:5:14 | 1 | macro_rules! uwu { | ---------------- when calling this macro ... 4 | uwu! { a a a c } | ^ no rules expected this token in macro call | +note: while trying to match `b` + --> macros.rs:2:12 + | +2 | (a a a b) => {}; + | ^ ```		2022-11-15 10:44:07 +01:00
