Rust Dependencies Visualizer

Generate ASCII art visualizations of your Rust project's dependency tree.

Usage

/rust-deps-visualizer [--depth N] [--features]

**Options:**

• `--depth N`: Limit tree depth (default: 3)
• `--features`: Show feature flags

Output Format

Simple Tree (Default)

my-project v0.1.0
├── tokio v1.49.0
│   ├── pin-project-lite v0.2.x
│   └── bytes v1.x
├── serde v1.0.x
│   └── serde_derive v1.0.x
└── anyhow v1.x

Feature-Aware Tree

my-project v0.1.0
├── tokio v1.49.0 [rt, rt-multi-thread, macros, fs, io-util]
│   ├── pin-project-lite v0.2.x
│   └── bytes v1.x
├── serde v1.0.x [derive]
│   └── serde_derive v1.0.x (proc-macro)
└── anyhow v1.x [std]

Implementation

**Step 1:** Parse Cargo.toml for direct dependencies

cargo metadata --format-version=1 --no-deps 2>/dev/null

**Step 2:** Get full dependency tree

cargo tree --depth=${DEPTH:-3} ${FEATURES:+--features} 2>/dev/null

**Step 3:** Format as ASCII art tree

Use these box-drawing characters:

• `├──` for middle items
• `└──` for last items
• `│ ` for continuation lines

Workflow

1. Check for Cargo.toml in current directory 2. Run `cargo tree` with specified options 3. Parse output and generate ASCII visualization 4. Optionally categorize by purpose (runtime, dev, build)
