Rust Deps Visualizer

Turns your Rust project's dependency tree into readable ASCII art diagrams. Runs cargo tree under the hood and formats the output with box-drawing characters, showing version numbers and optionally feature flags. You can limit the depth to avoid sprawl or categorize dependencies by type (runtime, dev, build). The visual size bars are a nice touch if you care about compile times and binary bloat. Honestly most useful when onboarding someone to a project or debugging why a transitive dependency snuck in. Beats squinting at raw cargo tree output, though the categorization feature assumes you'll manually tag things or parse them heuristically.

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
