- If your exercise implements macro-based testing (see [#392](https://github.com/exercism/rust/issues/392#issuecomment-343865993) and [`perfect-numbers.rs`](https://github.com/exercism/rust/blob/main/exercises/practice/perfect-numbers/tests/perfect-numbers.rs)), you will likely run afoul of a CI check which counts the `#[ignore]` lines and compares the result to the number of `#[test]` lines. To fix this, add a file `.meta/ignore-count-ignores` to disable that check for your exercise.
-- `README.md` may be [regenerated](https://github.com/exercism/legacy-docs/blob/main/maintaining-a-track/regenerating-exercise-readmes.md) from Exercism data. The generator will use the `description.md` from the exercise directory in the [problem-specifications repository](https://github.com/exercism/problem-specifications/tree/main/exercises), then any hints in `.meta/hints.md`, then the [Rust-specific instructions](https://github.com/exercism/rust/blob/main/config/exercise_readme.go.tmpl). The `## Source` section comes from the `metadata.yml` in the same directory. Convention is that the description of the source remains text and the link is both name and hyperlink of the markdown link.

- Be sure to add the exercise to an appropriate place in the `config.json` file. The position in the file determines the order exercises are sent. Generate a unique UUID for the exercise. Current difficulty levels in use are 1, 4, 7 and 10.
