RFC 3681 (tracking issue) proposes supporting default values on fields.

As I mentioned at RustWeek, I'd love to move toward having SemVer lints available in cargo-semver-checks on day 1 of new language features hitting stable Rust. This feature is a perfect candidate to trial that:

  • @estebank and I have already worked to identify the new SemVer hazards in this language feature
  • the cargo-semver-checks schema and lints we'd need are relatively straightforward
  • all we need is for rustdoc JSON to include the info we need.
