+   |                ^^^ expected an `Fn<()>` closure, found `()`
+   |
+   = help: the trait `Fn<()>` is not implemented for `()`
+   = note: wrap the `()` in a closure with no arguments: `|| { /* code */ }`
+   = note: required for the cast from `()` to the object type `dyn Fn()`
+
+error: aborting due to previous error
