Keep Dependency Updates Intentional
RUST-KEEP-DEPENDENCY-UPDATES-INTENTIONAL
Summary
Separate maintenance-only dependency refreshes from updates that change behavior, features, MSRV, or integration. Reviewable grouping lowers noise without hiding downstream risk.
Rule
Keep Rust dependency updates intentional and low-noise.
Why
Dependency updates can change parsing behavior, trait implementations, feature resolution, MSRV, platform support, compile time, and downstream integration even when the manifest requirement looks semver-compatible. Maintenance-only updates should be easy to review, while behavior-affecting updates deserve their own validation and release notes.
Grouped automation reduces review noise, but it should not hide semver-incompatible behavior or
raise minimum versions without a reason. Use dependency-management commands when they keep
Cargo.toml, lockfiles, and feature metadata consistent better than hand edits.
Helps
- Helps dependency maintenance stay reviewable without surprising downstream users.
Limits
Security fixes, yanked versions, and ecosystem breakage may require focused urgent updates. Keep the reason visible and validate the affected public surface.
Agent Instruction
Group routine Rust dependency updates, separate behavior-affecting updates, and use Cargo-aware
commands to preserve manifest consistency.Mechanisms
Supported by cargo update, cargo add, dependency bots, lockfile review, MSRV checks, feature
matrix checks, and semver or downstream tests.
