This can be simplified to just:
/// `ap` must not be used to access variable arguments after this call
library/core/src/ffi/va_list.rs
Outdated
| /// | ||
| /// - has a type that is ABI-compatible with the type `T` | ||
| /// - has a value that is a properly initialized value of type `T` | ||
| /// - there is a next variable argument available (i.e., the number of arguments already read from `ap` is less than the total number passed) |

I observed that PR146521 submitted two weeks ago resolved some documentation issues related to
VaListImpl, similar to the previous PR136969.This PR specifically adds requirements about argument availability for
VaListImpl::arg, and also adds safety descriptions to the three associated intrinsic APIs.
