I just realized I forgot to update these docs when adding from_exposed_addr.
Right now the docs say invalid and from_exposed_addr are both equivalent to a cast, and that is clearly not what we want (and is also not the case any more in terms of implementation since #97219).

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with r? rust-lang/libs-api @rustbot label +T-libs-api -T-libs to request review from a libs-api team reviewer. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

ptr::invalid is not equivalent to a int2ptr cast

I just realized I forgot to update these docs when adding `from_exposed_addr`.
Right now the docs say `invalid` and `from_exposed_addr` are both equivalent to a cast, and that is clearly not what we want.
