Rust Deps Visualizer

The rust-deps-visualizer skill generates interactive dependency graphs for Rust projects, mapping out crate relationships and version constraints directly from Cargo.toml files. It helps developers quickly identify transitive dependencies and visualize the structure of their software supply chain without manual parsing.

When to use it

• Audit a new Rust codebase to understand external library usage before committing to a project.
• Identify potential security vulnerabilities by visualizing outdated or vulnerable transitive crates.
• Debug complex dependency conflicts where multiple packages require incompatible versions of the same crate.
• Document system architecture for onboarding new team members unfamiliar with the specific dependencies.

Key capabilities

• Parses Cargo.toml files to extract direct and indirect dependencies.
• Renders interactive visualizations showing the hierarchy of Rust crates.
• Highlights version constraints and relationships between packages.
• Integrates seamlessly into development workflows for rapid dependency analysis.

Example prompts

• "Visualize the dependency tree for my current Rust project located at ./src/Cargo.toml."
• "Generate a graph showing all transitive dependencies for the tokio crate in this repository."
• "Identify and visualize any duplicate or conflicting version constraints in this Cargo manifest."

Tips & gotchas

Ensure your Cargo.lock file is up to date before running the visualizer, as it provides the most accurate version data. The tool focuses on structural relationships; for deep security scanning, combine this visualization with dedicated vulnerability scanners like cargo-audit.
