23 | | ^^^^^^^^^^^^^^^ implementation of `FnOnce` is not general enough |
24 | | | |
25 | = note: closure with signature `fn(&'2 i32) -> &i32` must implement `FnOnce<(&'1 i32,)>`, for any lifetime `'1`... | |
26 | = note: ...but it actually implements `FnOnce<(&'2 i32,)>`, for some specific lifetime `'2` | |
