These crates are shared with ChromeOS and used by other ChromeOS Rust projects. However since crosvm is refactoring this part of the code heavily, ChromeOS has pinned the version of some of these crates:
Modifications made here will not be available for other ChromeOS projects.
If you are looking for a place to add new ChromeOS-specific utilities, please consider libchromeos-rs.
If modifications to these crates cannot be avoided, consider manually updating the revision in the corresponding ebuild file, which may come with a significant need for refactoring.
Alternatively, for small changes consider adding a patch file into the corresponding ebuild file instead.
See b/229016539 for details.
