@tj-yazman Can you please describe the error you're seeing in more detail. This code looks correct to me.

Code seems to be broadly copied from https://doc.rust-lang.org/book/ch10-02-traits.html#fixing-the-largest-function-with-trait-bounds and there are various signals indicating this might be a spam, similar to #80773. Closing for now, but if the author does provide more explanation, we can reopen.
