Conversation
This commit adds `as_str` methods to `SplitWhitespace` and `SplitAsciiWhitespace` str iterators. The methods return the remainder, similar to `as_str` methods on `Chars` and other split iterators. This commit also makes fields of some iterators `pub(crate)`.

This PR adds
as_strmethods toSplitWhitespaceandSplitAsciiWhitespacestr iterators. The methods return the remainder, similar to
as_strmethods onCharsand other split iterators. This PR is a continuation of #75265, which addedas_strfor all other str split iterators.The feature gate for new methods is
#![feature(str_split_whitespace_as_str)].SplitWhitespaceandSplitAsciiWhitespaceuse iterators under the hood, so to implementas_strit's required to eitherpub(crate)into_inner,inner,inner_mut...) to some (all) iteratorsSplitWhitespaceandSplitAsciiWhitespaceThis PR uses the 1. approach since it's easier to implement and requires fewer changes (and no changes to the public API). If you think that's not the right way, please, tell me.
