| Status              | unmaintained                |
| Package             | `sass-rs`                      |
| Version             | `0.2.2`                   |
| URL                 | [https://github.com/compass-rs/sass-rs/issues/83](https://github.com/compass-rs/sass-rs/issues/83) |
| Date                | 2021-04-07                         |

The `sass-rs` crate is not maintained anymore as libsass is deprecated.
Consider using https://github.com/connorskees/grass or https://github.com/kaj/rsass instead.
(Author&#39;s recomendation.)

See [advisory page](https://rustsec.org/advisories/RUSTSEC-2021-0136.html) for additional details.
