Why explicitly non-dispatchable methods in Iterator are dispatchable?

Rust reference object-safety confused me for a while, and says:

Explicitly non-dispatchable functions require:

Have a where Self: Sized bound (receiver type of Self (i.e. self) implies this).

How to use std::cmp::Reverse with binary_search_by_key? Example: Rust-Playground

The documentation to Rust's Vec::binary_search_by_key says:

Assumes that the slice is sorted by the key, for instance with sort_by_key using the same key extraction function.
