| error[E0038]: the trait `FromResidual` is not dyn compatible |

| | ^^^^^^^^^^^^ `FromResidual` is not dyn compatible |
| | |
| note: for a trait to be dyn compatible it needs to allow building a vtable |

| | ------------ this trait is not dyn compatible... |
| LL | fn from_residual(residual: R) -> Self; |
| | ^^^^^^^^^^^^^ ...because associated function `from_residual` has no `self` parameter |
| help: consider turning `from_residual` into a method by giving it a `&self` argument |
| | |
| LL | fn from_residual(&self, residual: R) -> Self; |
| | ++++++ |
| help: alternatively, consider constraining `from_residual` so it does not apply to trait objects |
| | |
| LL | fn from_residual(residual: R) -> Self where Self: Sized; |
