## Code Examples

### Example 1: Basic Setup

```rust
// Basic Clippy setup
// Demonstrates fundamental usage patterns
// Shows proper initialization and configuration

// Core setup code
function basicSetup() {
  // Initialize framework
  // Configure basic options
  // Return configured instance
}

// Usage example
const instance = basicSetup();
```

### Example 2: Configuration

```rust
// Configuration example for Clippy
// Shows how to properly configure
// Includes common options and patterns

// Configuration object
const config = {
  option1: 'value1',
  option2: 'value2',
  advanced: {
    setting1: true,
    setting2: false
  }
};

// Apply configuration
function applyConfig(config) {
  // Validation logic
  // Application logic
  // Return result
}
```

### Example 3: Advanced Pattern

```rust
// Advanced usage pattern
// Demonstrates sophisticated techniques
// Shows best practices in action

function advancedPattern() {
  // Setup phase
  // Execution phase
  // Cleanup phase
}
```

### Example 4: Integration

```rust
// Integration with other tools
// Shows real-world usage
// Demonstrates interoperability

function integrationExample() {
  // Setup integration
  // Execute workflow
  // Handle results
}
```

### Example 5: Error Handling

```rust
// Proper error handling approach
// Defensive programming patterns
// Graceful degradation

function withErrorHandling() {
  try {
    // Main logic
  } catch (error) {
    // Error recovery
  } finally {
    // Cleanup
  }
}
```

### Example 6: Performance Optimization

```rust
// Performance-optimized implementation
// Shows efficiency techniques
// Demonstrates best practices

function optimizedApproach() {
  // Efficient implementation
  // Resource management
  // Performance monitoring
}
```

### Example 7: Testing

```rust
// Testing approach for Clippy
// Unit test examples
// Integration test patterns

function testExample() {
  // Test setup
  // Execution
  // Assertions
  // Teardown
}
```

### Example 8: Production Usage

```rust
// Production-ready implementation
// Includes monitoring and logging
// Error recovery and resilience

function productionExample() {
  // Production configuration
  // Monitoring setup
  // Error handling
  // Logging
}
```

## Best Practices

1. **Follow conventions** - Adhere to established naming and structural patterns for consistency
2. **Configure appropriately** - Set up framework configuration that matches project requirements
3. **Validate inputs** - Always validate and sanitize inputs before processing
4. **Handle errors gracefully** - Implement comprehensive error handling and recovery
5. **Document decisions** - Comment configuration choices and non-obvious implementations
6. **Test thoroughly** - Write comprehensive tests for all functionality
7. **Optimize performance** - Profile and optimize critical paths
8. **Maintain security** - Follow security best practices and guidelines
9. **Keep updated** - Regularly update framework and dependencies
10. **Monitor production** - Implement logging and monitoring for production systems

## Common Pitfalls

1. **Incorrect configuration** - Misconfiguration leads to unexpected behavior and bugs
2. **Missing error handling** - Not handling edge cases causes production issues
3. **Poor performance** - Not optimizing leads to scalability problems
4. **Inadequate testing** - Insufficient test coverage misses bugs
5. **Security vulnerabilities** - Not following security best practices exposes risks
6. **Tight coupling** - Poor architecture makes maintenance difficult
7. **Ignoring warnings** - Dismissing framework warnings leads to future problems
8. **Outdated dependencies** - Using old versions exposes security risks
9. **No monitoring** - Lack of observability makes debugging difficult
10. **Inconsistent standards** - Team inconsistency reduces code quality
