Rust does not have `null`, but it is not ignorant of the importance of

Technically, there is std::ptr::null so this sentence is technically incorrect. Should we add a footnote expanding on this?

I personally think its better to leave it like that since it helps get the point across more easily. Its kinda the same way you teach some things in math, no need to overcomplicate the explanation for beginners.

I think if this hasn't been touched for 3 years, it probably won't, maybe because of the exact reason you stated :) Still, I would like to think that I was technically correct, even if that sort of pedantry isn't well placed in here. Though, to be fair, I did say a footnote¹.

This point is important at least for people with C/C++ experience. Main question would be difference between std::ptr::null and just zeroing the pointer.
In another words, if std::ptr::null is a special value (not equal to 0).
