I've made this patch almost a year ago, so the rename and the behavior change are in one commit, sorry 😅

This fixes #84974, as it's required to make other changes work.

This PR

  • Renames as_str method of string Split* iterators to remainder (it seems like the as_str name was confusing to users)
  • Makes remainder return Option<&str>, to distinguish between "the iterator is exhausted" and "the tail is empty", this was required on the tracking issue

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 @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. 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
