By name: rust-lint description: Rust code quality check - Use Clippy and Rustfmt to ensure Rust code standards and performance optimization
Rust Lint Skill
📋 Overview
Use Rust official toolchain to check code quality:
- Clippy: Smart code checks (450+ rules)
- Rustfmt: Code formatting
🔧 Prerequisites
| Tool | Min Version | Installation |
|---|---|---|
| Rust | 1.70+ | curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh |
| Clippy | - | rustup component add clippy |
| Rustfmt | - | rustup component add rustfmt |
🚀 Usage
Run Clippy:
.\.agent\skills\rust-lint\scripts\lint.ps1
Auto-fix:
.\.agent\skills\rust-lint\scripts\lint.ps1 -Fix
Format code:
.\.agent\skills\rust-lint\scripts\format.ps1
🎯 What It Checks
Performance Optimization
- ✅ Avoid unnecessary clones
- ✅ Use iterators instead of loops
- ✅ String handling optimization
- ✅ Collection operation efficiency
Security
- ✅ Unused unsafe code
- ✅ Integer overflow detection
- ✅ Null pointer dereference
- ✅ Lifetime issues
Idiomatic Rust
- ✅ Pattern matching recommendations
- ✅ Option/Result usage
- ✅ Error handling best practices
- ✅ Trait implementation suggestions

# Warning level lints
warn = [
"clippy::pedantic",
"clippy::nursery",
]
# Denied lints
deny = [
"clippy::unwrap_used",
