error[E0599]: the function or associated item `call` exists for struct `Wrapper<function>`, but its trait bounds were not satisfied

   |
   = note: the following trait bounds were not satisfied:
           `Wrapper<function>: Fn<_>`
           which is required by `&Wrapper<function>: Fn<_>`
note: the trait `Fn` must be implemented
  --> $SRC_DIR/core/src/ops/function.rs:LL:COL
   = help: items from traits can only be used if the trait is implemented and in scope
   = note: the following trait defines an item `call`, perhaps you need to implement it:
           candidate #1: `Fn`

error: aborting due to 3 previous errors
