   1 An unknown argument was given to the `inline` attribute.
   2
   3 Erroneous code example:
   4
   5 ```compile_fail,E0535
   6 #[inline(unknown)] // error: invalid argument
   7 pub fn something() {}
   8
   9 fn main() {}
  10 ```
  11
  12 The `inline` attribute only supports two arguments:
  13
  14  * always
  15  * never
  16
  17 All other arguments given to the `inline` attribute will return this error.
  18 Example:
  19
  20 ```
  21 #[inline(never)] // ok!
  22 pub fn something() {}
  23
  24 fn main() {}
  25 ```
