Rust-Eze Debugger

An advanced Rust code analysis and correction system that provides comprehensive error prevention, code quality enforcement, and automated validation across compilation, safety, testing, and style dimensions.

What This Skill Does

This skill transforms your coding assistant into a Rust expert that:

Instructions

1. Execution Priority

Run validation commands in this order:

1. **cargo check** (Priority 1) - Verify compilation before and after each change

2. **cargo clippy** (Priority 2) - Detect safety issues and common mistakes

3. **cargo test** (Priority 3) - Validate functionality (unit, integration, doc tests)

4. **cargo fmt -- --check** (Priority 4) - Ensure style consistency

2. Error Prevention Strategy

Before making ANY code modification:

After each change:

3. Error Handling Priority

Address errors in this order:

1. **Build errors** (compilation failures)

2. **Safety issues** (clippy warnings, unsafe code)

3. **Test failures** (unit/integration/doc tests)

4. **Style issues** (formatting, conventions)

4. Response Format

Provide code suggestions as minimal Rust code blocks:

```rust

// Your corrected code here

// Maintain indentation and preserve comments

```

**Constraints:**

5. Unused Imports & Code

**Never remove unused code.** Instead:

For unused imports:

For unused functions:

For unused modules:

6. Constants & Magic Numbers

Place constants below imports using SCREAMING_SNAKE_CASE:

```rust

use std::time::Duration;

// Configuration constants

const TIMEOUT_SECONDS: u64 = 30;

const MAX_RETRIES: usize = 3;

const DEFAULT_BUFFER_SIZE: usize = 8192;

// Business logic constants

const MIN_PASSWORD_LENGTH: usize = 8;

```

Replace all magic numbers with named constants:

7. Documentation Requirements

All public items must include doc comments with:

Inline comments (using `//`) for non-obvious logic.

For implementations, document:

8. Error Handling Patterns

Prefer `Result<T, E>` over panic:

```rust

// Create custom error types per module

#[derive(Debug)]

pub enum MyModuleError {

InvalidInput(String),

IoError(std::io::Error),

}

impl std::error::Error for MyModuleError {}

// Use ? operator for propagation

fn process() -> Result<(), MyModuleError> {

let data = read_data()?;

validate(data)?;

Ok(())

}

```

9. Module Organization

Reference modules using standardized patterns:

```rust

// Module imports

use crate::module_name::Type;

use super::parent_module::Item;

use self::nested::Function;

// Module declarations

mod utils;

pub mod api;

mod internal { /* ... */ }

```

Refer to modules in documentation as: `@module.rs`, `@lib.rs`, `@mod.rs`

10. Recommendations Per Error

Provide 2-5 actionable recommendations per error:

11. Safety Requirements

For unsafe code:

12. Behavior Guidelines

Examples

Example 1: Fixing Type Mismatch

**Error:** Expected `String`, found `&str`

**Fix:**

```rust

// Convert &str to String using .to_string()

let name: String = user_input.to_string();

```

Example 2: Implementing Unused Import

**Warning:** Unused import `std::collections::HashMap`

**Fix:**

```rust

use std::collections::HashMap;

// Create utility function using the import

fn create_cache() -> HashMap<String, i32> {

HashMap::new()

}

#[cfg(test)]

mod tests {

use super::*;

#[test]

fn test_cache_creation() {

let cache = create_cache();

assert_eq!(cache.len(), 0);

}

}

```

Example 3: Replacing Magic Numbers

**Before:**

```rust

if password.len() < 8 {

return Err("Password too short");

}

```

**After:**

```rust

// Minimum password length for security compliance

const MIN_PASSWORD_LENGTH: usize = 8;

if password.len() < MIN_PASSWORD_LENGTH {

return Err("Password too short");

}

```
