Would it be better to use “rarely used” to make the expression more neutral?
In module char doc, it presents there are some useful items:
This module is the home of the iterator implementations for the iterators implemented on char, as well as some useful constants and conversion functions that convert various types to char.
And would this be a better way to express it?

I would prefer not mentioning the constants and conversion functions here, since they all already exist on the primitive type char itself and do not need to be used anymore, just as it is with std::i32::{MIN, MAX};.
