🦀 rust-base

A modern Rust boilerplate template with async runtime, environment management, and containerization support.

✨ Features

• Rust 2024 Edition with stable toolchain
• Async Runtime powered by Tokio
• Environment Configuration with dotenvy
• Reproducible Development using devenv (Nix)
• Docker Ready with optimized multi-stage builds
• Development Tools pre-configured (clippy, rustfmt, rust-analyzer)

🚀 Quick Start

# Clone and setup
git clone https://github.com/tencat-dev/rust-base.git my-project
cd my-project
cp .env.example .env

# Run with devenv (recommended)
devenv shell
cargo run

# Or run with cargo directly
cargo run

# Or use Docker
docker build -t my-project .
docker run --env-file .env my-project

📦 Installation

Option 1: devenv (Recommended)

# Install Nix and devenv
curl -L https://install.determinate.systems/nix | sh
nix profile install nixpkgs#devenv

# Enter development environment
devenv shell

Option 2: Local Rust

# Install Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup component add clippy rustfmt rust-analyzer

⚙️ Configuration

Create .env from template and configure as needed:

# .env
HOST=localhost
PORT=8080
RUST_LOG=info

🔨 Development

Running the Application

# Development mode
cargo run

# With file watching
cargo watch -x run

# Release mode
cargo build --release
./target/release/rust-base

Code Quality

# Format code
cargo fmt

# Lint code
cargo clippy

# Run tests
cargo test

# Generate documentation
cargo doc --open

Docker Usage

# Build image
docker build -t rust-base .

# Run container
docker run --env-file .env rust-base

# Development with volume
docker run -v $(pwd):/app --env-file .env rust-base

🧪 Testing

# Run all tests
cargo test

# Run with output
cargo test -- --nocapture

# Integration tests
cargo test --test integration

Environment Variables

Required environment variables:

• HOST: Server hostname
• PORT: Server port (optional, defaults in code)
• RUST_LOG: Logging level (optional)

🤝 Contributing

1. Fork the repository
2. Create a feature branch: git checkout -b feature/new-feature
3. Make changes and test: cargo test && cargo clippy
4. Format code: cargo fmt
5. Commit changes: git commit -m 'Add new feature'

🔧 Troubleshooting

Common Issues

Environment variables not loading:

# Ensure .env exists
cp .env.example .env

Build failures:

rustup update

# Clear cache
cargo clean

Docker issues:

# Rebuild without cache
docker build --no-cache -t rust-base .
