description	Practical guidance for writing, refactoring, and reviewing fast, reliable, and maintainable Rust code.

fast-rust

Concise guidance for high-quality Rust engineering, balancing correctness, maintainability, and performance.

Purpose and Triggers

• Writing new code, refactoring, reviewing, or designing public APIs/CLIs.
• Rust or files with .rs.
• Prefer clear boundaries, error semantics, and evolvability.

Decision Order

1. Correctness and clear boundaries
2. Readability and maintainability
3. Extensibility and evolution cost
4. Performance and optimization

Workflow

1. Locate the relevant topic below.
2. Apply the guidance and examples.
3. Read the reference if you need more detail.
