Crates.io Publishing

Notes on publishing rsconstruct to crates.io.

Version Limits

There is no limit on how many versions can be published to crates.io. You can publish as many releases as needed without worrying about quota or cleanup.

Pruning Old Releases

Crates.io does not support deleting published versions. Once a version is uploaded, it exists permanently.

The only removal mechanism is yanking (cargo yank --version 0.1.0), which:

• Prevents new projects from adding a dependency on the yanked version
• Does not break existing projects that already depend on it (they continue to download it via their lockfile)
• Does not delete the crate data from the registry

Yanking should only be used for versions with security vulnerabilities or serious bugs, not for general housekeeping.

Publishing a New Version

1. Update the version in Cargo.toml
2. Run cargo publish --dry-run to verify
3. Run cargo publish to upload
