   1 A non-`'static` lifetime was used in a const generic. This is currently not
   2 allowed.
   3
   4 Erroneous code example:
   5
   6 ```compile_fail,E0771
   7 #![feature(adt_const_params)]
   8
   9 fn function_with_str<'a, const STRING: &'a str>() {} // error!
  10 ```
  11
  12 To fix this issue, the lifetime in the const generic need to be changed to
  13 `'static`:
  14
  15 ```
  16 #![feature(adt_const_params)]
  17
  18 fn function_with_str<const STRING: &'static str>() {} // ok!
  19 ```
