What are the best practices for Rust project structure?

Rust project structure best practices: • Standard directory layout • Clear module organization • Separation of concerns • Documentation and examples • Testing strategy Standard structure: project/ ├── Cargo.toml # Package manifest ├── Cargo.lock # Dependency lock file ├── README.md # Project documentation ├── LICENSE # License file ├── src/ │ ├── lib.rs # Library root (for libraries) │ ├── main.rs # Binary root (for executables) │ ├── bin/ # Additional binaries │ └── modules/ # Module files ├── tests/ # Integration tests ├── examples/ # Example code ├── benches/ # Benchmarks └── docs/ # Additional documentation Module organization: // lib.rs pub mod config; pub mod database; pub mod api; pub use config::Config; pub use database::Database; // main.rs use myproject::{Config, Database}; fn main() { let config = Config::load(); let db = Database::connect(&config); } Cargo.toml structure: [package] name = "myproject" version = "0.1.0" edition = "2021" authors = ["Your Name "] license = "MIT" description = "A brief description" repository = "https://github.com/user/repo" keywords = ["rust", "example"] categories = ["development-tools"] [dependencies] serde = { version = "1.0", features = ["derive"] } tokio = { version = "1.0", features = ["full"] } [dev-dependencies] tokio-test = "0.4" Best practices: • Use descriptive module names • Keep functions small and focused • Document public APIs • Write comprehensive tests • Use semantic versioning • Include examples and benchmarks
