(rustdoc) usize and isize associated items only available on 64-bit. #150536

Summary
doc_cfg labels all associated items of usize and isize with Available on 64-bit only., even when the item in question is portable and has a constant signature across targets (e.g. all methods).
Currently applies to nightly and beta.
What I would call optimal: Only associated constants that are formally-platform-dependent (e.g. MIN and MAX) should be labelled.
Possible fix: Move portable item implementations out of the cfg'ed impl blocks. This would maybe require splitting the int_impl and uint_impl macros, e.g. int_impl_conditional and int_impl_portable.

Thanks for reporting. This is a duplicate of #149786.
usizedocs show everything as “Available on 64-bit only” #149786bjoernager commentedon Dec 31, 2025
Thanks for letting me know. I must've missed it when I looked for an existing issue. :/
