📝 Walkthrough

Walkthrough

The changes refactor dependency feature handling from Vec<String> to BTreeSet<String> across multiple modules. The CargoTomlDependency struct is updated to use BTreeSet for features, and all code that creates, merges, or populates dependency features is adjusted accordingly.

Changes

Cohort / File(s)	Summary
Struct Definition & Serialization crates/module-parser/src/config.rs	Updated CargoTomlDependency.features field from Vec<String> to BTreeSet<String>, including serde attributes to skip serialization when empty.
Feature Population from Metadata crates/module-parser/src/metadata.rs	Modified get_dependencies to extract enabled features from cargo metadata's resolve graph and populate CargoTomlDependency.features. Added unit test gets_enabled_features_for_located_packages to verify feature set population for aliased dependencies.
Feature Merging Logic crates/cli/src/mod/add.rs	Updated merge_dependency_metadata to extend existing feature sets using extend() instead of conditional pushing. Adjusted tests to use BTreeSet::from([...]) for feature construction.
Feature Mutation Operations crates/cli/src/common.rs	Changed create_required_deps to mutate feature sets using insert() for existing dependencies rather than reassigning vectors. Updated imports to include BTreeSet.

Poem

🐰 From vectors scattered, now sets align,
Features bundled, pristine and fine,
No duplicates hop through our store,
A BTreeSet organizes more and more! 🌳✨

🚥 Pre-merge checks | ✅ 2 | ❌ 1

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.

Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title directly describes the main feature change: dependency features are now extracted and used from the generated manifest instead of being ignored or hardcoded.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}
