| An attribute was given an invalid number of arguments | |
| Erroneous code example: | |
| ```compile_fail,E0805 | |
| #[inline()] // error! should either have a single argument, or no parentheses | |
| fn foo() {} | |
| #[inline(always, never)] // error! should have only one argument, not two | |
| fn bar() {} | |
| ``` | |
| To fix this, either give the right number of arguments the attribute needs. | |
| In the case of inline, this could be none at all: | |
| ``` | |
| #[inline] | |
| fn foo() {} | |
| ``` | |
| or only one: | |
| ``` | |
| #[inline(always)] | |
| fn foo() {} | |
| ``` |
