Rust Deps Visualizer

Generates ASCII art dependency trees for Rust projects by wrapping cargo tree with visualization options. Run it with --depth to control how deep the tree goes and --features to see which feature flags are active on each crate. The output uses box-drawing characters for a clean terminal-friendly display. What makes this worth using is the optional categorization view that groups dependencies by purpose (runtime, dev, build) and the size visualization that shows how much each dependency contributes to your compile times. Good for auditing what's actually in your dependency graph or explaining your project's structure to teammates.

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
