SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Idiomatic Rust patterns and best practices to improve safety, performance, and maintainability across Rust codebases, covering ownership, error handling, patterns, and concurrency.

Core Features & Use Cases

  • Ownership and borrowing rules to prevent data races at compile time.
  • Structured error handling with thiserror and anyhow, explicit pattern matching, and robust propagation.
  • Enums, pattern matching, and state modeling to make illegal states unrepresentable.
  • Traits, generics, and zero-cost abstractions for flexible and safe APIs.
  • Safe concurrency using Arc<Mutex<T>> and channels for parallel workloads.
  • Module organization and minimal public surface to maintain clean crates.
  • Guidance on unsafe code boundaries and when to prefer safe alternatives.

Quick Start

Apply idiomatic Rust patterns to your codebase by aligning ownership, error handling, and concurrency with best practices.

Frequently Asked Questions about rust-patterns

FAQPage Schema
What are the best practices for Rust error handling with thiserror and anyhow?▼

Idiomatic Rust concurrency patterns use Arc<Mutex<T>> to safely share mutable state across threads and channels for message passing. These patterns prevent data races at compile time while maintaining safe parallel workloads.

How do I use Rust ownership and borrowing rules to prevent data races?▼

Rust ownership and borrowing rules prevent data races at compile time by enforcing strict lifetimes and mutable reference constraints. Applying these idiomatic patterns ensures memory safety without needing a garbage collector.

When should I use unsafe code in Rust and what are the boundaries?▼

Rust unsafe code should be minimized and isolated behind safe abstraction boundaries. You should prefer safe alternatives and idiomatic patterns whenever possible, using unsafe only for FFI, hardware access, or performance-critical sections.

How do I model state and make illegal states unrepresentable in Rust?▼

Modeling state in Rust uses enums and explicit pattern matching to make illegal states unrepresentable. This idiomatic approach leverages the type system to enforce valid state transitions and prevent logic errors at compile time.

Does this Rust pattern guidance apply to large crates and modular structures?▼

Yes, this Rust pattern guidance applies to large crates by enforcing module organization and minimal public surface area. It helps maintain clean crate structures and scalable codebases from small utilities to complex projects.
