cargo-shed

cargo-shed 0.1.0

First public release of cargo-shed, a Cargo subcommand and Rust library that helps identify dependency bloat, risky feature selections, duplicate crate versions, and safe cleanup opportunities in Rust projects.

cargo-shed is intentionally conservative. It analyzes Cargo.toml, Cargo.lock, and Rust source files under src/ and tests/, but it does not compile the project, execute build scripts, or run any project code.

Features

• Detects overly broad dependency feature selections (such as tokio = { features = ["full"] })
• Identifies dependencies with unnecessary default features enabled
• Finds duplicate crate versions in the dependency graph
• Reports potentially unused dependencies
• Generates actionable recommendations with supporting evidence
• Provides optional automatic fixes for selected issues

Installation
