Note

The 370 ignored documentation tests are not included here.

Rust’s documentation and testing tooling considers all snippets of code in the generated documentation to be a test by default, and snippets that are not meant to be valid Rust code (or Rust code at all) would cause test failures if not ignored explicitly.

Because of that, we don’t consider ignored documentation tests to be valid tests that were skipped by our testing infrastructure: we consider them not to be tests at all.
