| ## Passes |
| |
| Rustdoc has a concept called "passes". These are transformations that |
| `rustdoc` runs on your documentation before producing its final output. |
| |
| Customizing passes is **deprecated**. The available passes are not considered stable and may |
| change in any release. |
| |
| In the past the most common use case for customizing passes was to omit the `strip-private` pass. |
| You can do this more easily, and without risk of the pass being changed, by passing |
| [`--document-private-items`](command-line-arguments.md#--document-private-items-show-items-that-are-not-public). |
