| | ^^ | |
| | | |
| = note: fragment specifiers must be provided | |
| = help: valid fragment specifiers are `ident`, `block`, `stmt`, `expr`, `pat`, `ty`, `lifetime`, `literal`, `path`, `meta`, `tt`, `item` and `vis`, along with `expr_2021` and `pat_param` for edition compatibility | |
| help: try adding a specifier here | |
