# Fast Rust

Fast Rust provides guidance for writing, refactoring, and reviewing Rust code with attention to correctness, maintainability, and performance. Use it when designing APIs, handling errors, or improving compile and runtime behavior.

**Install:**

```bash
npx degit https://github.com/PsiACE/skills/tree/main/skills/fast-rust ~/.claude/skills/fast-rust
```

## README

# 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.

## Topics

| Topic | Guidance | Reference |
| --- | --- | --- |
| Error Design | Design error boundaries and semantics before propagation | [references/error-design.md](references/error-design.md) |
| Compilation | Optimize build time and release performance with measured changes | [references/compilation-optimization.md](references/compilation-optimization.md) |
| Type Exercise | Type-level exercise for expression engines and dispatch | [references/type-exercise.md](references/type-exercise.md) |
