CUT

Rust

This page covers current (2025/2026) best practices for Rust projects.

Bootstrap

Create a binary crate:

cargo new my-app --bin

Create a library crate:

cargo new my-lib --lib

New projects use the Rust 2024 edition by default.

Tooling

Category	Tool	Notes
Toolchain	rustup	Install with the rustup script.
Formatter	rustfmt	Run cargo fmt.
Linter	clippy	Run cargo clippy --all-targets --all-features.
Testing	cargo test	Unit tests in #[cfg(test)], integration tests in tests/.
Async runtime	tokio	The standard choice.

Use cargo clippy -- -D warnings in CI.

Workspaces

Use a Cargo workspace for projects with multiple crates. Declare members in the root Cargo.toml.

workspace-root/
├── Cargo.toml
└── crates/
    ├── app/
    └── core/

Web Frameworks

Framework	Best For	Notes
Axum 0.8	Most Rust web apps	Most popular. Tokio team.
actix-web	High-throughput services	Slightly faster in benchmarks.
Rocket	Developer experience	Excellent ergonomics.

Use Axum for new web services.

Error Handling

Use thiserror for library error types. Use anyhow for application-level errors. The ? operator propagates errors.

Desktop and WASM

• Use Tauri 2 for cross-platform desktop apps with a web frontend.
• Use wasm-pack and wasm-bindgen for WebAssembly.

Related Technologies

• serde and serde_json for serialization.
• clap for command-line interfaces.
• tracing and tracing-subscriber for structured logging.
• sqlx for compile-time checked SQL.
• tonic for gRPC.
• criterion for benchmarks.
