📦 cargo-autodd
A Cargo subcommand that automatically manages dependencies in your Rust projects.
🔍 Overview
cargo-autodd simplifies Rust dependency management by automatically adding required crates to your Cargo.toml based on use statements, extern crate declarations, and direct references in your code.

✨ Features
- 🔎 Scans Rust source files for imports and direct references
- 🤖 Automatically detects required dependencies
- ⬆️ Updates Cargo.toml with the latest stable versions (including patch versions)
- 🗑️ Removes unused dependencies
- 📊 Generates dependency usage reports
- 🔒 Checks for security vulnerabilities
- 🏢 Supports Cargo workspaces and monorepo structures
- 🛡️ Handles internal crates with path dependencies correctly
- 🐛 Debug mode for detailed analysis
- 🔍 Detects direct references without use statements (e.g.,
serde_json::Value) - 🔄 Preserves original crate names (handles dashes and underscores correctly)
📥 Installation
⚙️ Requirements
- 🦀 Rust 1.56.0 or later
- 📦 Cargo
🚀 Usage
Command Line Interface
# Show help information
# Analyze and update dependencies in the current project
# Run with debug mode for detailed analysis
# or
Update Dependencies
# Check and update all dependencies to their latest versions
Generate Reports
# Generate a detailed dependency usage report
Security Check
# Check for security vulnerabilities
Monorepo Usage
# Run in the root of your workspace to analyze all crates
# Run in a specific crate directory within the workspace
When using cargo-autodd in a monorepo:
- Internal crates with
pathdependencies are automatically detected - The tool respects
publish = falsesettings - Dependencies are correctly managed across the workspace
Debug Mode
In debug mode, the following detailed information is displayed:
- 🔍 Path of detected Rust files
- 📝 Content of each line being processed
- 🔎 Detected
usestatements and base crate names - 📦 Details of nested imports
- 🔧 Detection of
extern cratestatements - 📊 Analysis results of each file
- 📋 Final list of crate references
🔄 How It Works
- 📝 Analyzes your Rust source files
- 🔍 Detects import statements, external crate declarations, and direct references
- ⚡ Updates Cargo.toml with required dependencies
- ✅ Verifies changes with
cargo check - 🔒 Checks for security vulnerabilities
- 📊 Generates detailed reports about dependency usage
🏢 Monorepo Support
cargo-autodd fully supports Cargo workspaces and monorepo structures:
- 🔄 Correctly detects and handles internal crates within a workspace
- 🛡️ Respects
publish = falsesettings for internal crates - 🔗 Properly handles path dependencies in both standard and inline table formats:
# Both formats are supported: = { = "../internal-crate" } [] = "../another-internal-crate" - 🚫 Avoids searching for internal crates on crates.io
- 🧩 Works with workspace inheritance for dependency management
This ensures that your internal crates that aren't meant to be published to crates.io are handled correctly, avoiding errors like Crate 'internal_crate' not found on crates.io.
