Rust invoke trait method on generic type parameter

Question

Suppose I have a rust trait that contains a function that does not take a &self parameter. Is there a way for me to call this function based on a generic type parameter

Answer 1

Unfortunately, this isn't currently possible. It used to be, based on a implementation detail, however that was removed in favor of eventually implementing a proper way of doing this.

When it is eventually implemented, it may end up looking something like this: TypeTrait::::type_id(), however there is, currently, no syntax set in stone.

This is a known case and one that is fully intended to be supported, it is just unfortunate that it currently is not possible.
