From https://quinedot.github.io/rust-learning/dyn-trait-impls.html: Why is this a problem? Couldn't the erased type's vtable for Trait have a pointer to its implementation of no_receiver()? The function pointed to by the vtable shouldn't have to have a receiver, right?

Explain why functions with no receiver are non-dispatchable?

How would you call it? The &self param is a fat pointer that contains the vtable pointer, so you need it to get the vtable.
