 # RustFS Project Cursor Rules
 
+## ⚠️ CRITICAL DEVELOPMENT RULES ⚠️
+
+### 🚨 NEVER COMMIT DIRECTLY TO MASTER/MAIN BRANCH 🚨
+- **This is the most important rule - NEVER modify code directly on main or master branch**
+- **Always work on feature branches and use pull requests for all changes**
+- **Any direct commits to master/main branch are strictly forbidden**
+- Before starting any development, always:
+  1. `git checkout main` (switch to main branch)
+  2. `git pull` (get latest changes)
+  3. `git checkout -b feat/your-feature-name` (create and switch to feature branch)
+  4. Make your changes on the feature branch
+  5. Commit and push to the feature branch
+  6. Create a pull request for review
+
 ## Project Overview
 RustFS is a high-performance distributed object storage system written in Rust, compatible with S3 API. The project adopts a modular architecture, supporting erasure coding storage, multi-tenant management, observability, and other enterprise-level features.

-### 2. Naming Conventions
+### 2. **🔧 MANDATORY Code Formatting Rules**
+
+**CRITICAL**: All code must be properly formatted before committing. This project enforces strict formatting standards to maintain code consistency and readability.
+
+#### Pre-commit Requirements (MANDATORY)
+
+Before every commit, you **MUST**:
+
+1. **Format your code**:
+   ```bash
+   cargo fmt --all
+   ```
+
+2. **Verify formatting**:
+   ```bash
+   cargo fmt --all --check
+   ```
+
+3. **Pass clippy checks**:
+   ```bash
+   cargo clippy --all-targets --all-features -- -D warnings
+   ```
+
+4. **Ensure compilation**:
+   ```bash
+   cargo check --all-targets
+   ```
+
+#### Quick Commands
+
+Use these convenient Makefile targets for common tasks:
+
+```bash
+# Format all code
+make fmt
+
+# Check if code is properly formatted
+make fmt-check
+
+# Run clippy checks
+make clippy
+
+# Run compilation check
+make check
+
+# Run tests
+make test
+
+# Run all pre-commit checks (format + clippy + check + test)
+make pre-commit
+
+# Setup git hooks (one-time setup)
+make setup-hooks
+```
+
+#### 🔒 Automated Pre-commit Hooks
+
+This project includes a pre-commit hook that automatically runs before each commit to ensure:
+
+- ✅ Code is properly formatted (`cargo fmt --all --check`)
+- ✅ No clippy warnings (`cargo clippy --all-targets --all-features -- -D warnings`)
+- ✅ Code compiles successfully (`cargo check --all-targets`)
+
+**Setting Up Pre-commit Hooks** (MANDATORY for all developers):
+
+Run this command once after cloning the repository:
+
+```bash
+make setup-hooks
+```
+
+Or manually:
+
+```bash
+chmod +x .git/hooks/pre-commit
+```
+
+#### 🚫 Commit Prevention
+
+If your code doesn't meet the formatting requirements, the pre-commit hook will:
+
+1. **Block the commit** and show clear error messages
+2. **Provide exact commands** to fix the issues
+3. **Guide you through** the resolution process
+
+Example output when formatting fails:
+
+```
+❌ Code formatting check failed!
+💡 Please run 'cargo fmt --all' to format your code before committing.
+
+🔧 Quick fix:
+   cargo fmt --all
+   git add .
+   git commit
+```

-### 3. Documentation Comments
+### 4. Type Declaration Guidelines
+- **Prefer type inference over explicit type declarations** when the type is obvious from context
+- Let the Rust compiler infer types whenever possible to reduce verbosity and improve maintainability
+- Only specify types explicitly when:
+  - The type cannot be inferred by the compiler
+  - Explicit typing improves code clarity and readability
+  - Required for API boundaries (function signatures, public struct fields)
+  - Needed to resolve ambiguity between multiple possible types
+
+**Good examples (prefer these):**
+```rust
+// Compiler can infer the type
+let items = vec![1, 2, 3, 4];
+let config = Config::default();
+let result = process_data(&input);
+
+// Iterator chains with clear context
+let filtered: Vec<_> = items.iter().filter(|&&x| x > 2).collect();
+```
+
+**Avoid unnecessary explicit types:**
+```rust
+// Unnecessary - type is obvious
+let items: Vec<i32> = vec![1, 2, 3, 4];
+let config: Config = Config::default();
+let result: ProcessResult = process_data(&input);
+```
+
+**When explicit types are beneficial:**
+```rust
+// API boundaries - always specify types
+pub fn process_data(input: &[u8]) -> Result<ProcessResult, Error> { ... }
+
+// Ambiguous cases - explicit type needed
+let value: f64 = "3.14".parse().unwrap();
+
+// Complex generic types - explicit for clarity
+let cache: HashMap<String, Arc<Mutex<CacheEntry>>> = HashMap::new();
+```

+ - **🚨 CRITICAL: NEVER modify code directly on main or master branch - THIS IS ABSOLUTELY FORBIDDEN 🚨**
+ - **⚠️ ANY DIRECT COMMITS TO MASTER/MAIN WILL BE REJECTED AND MUST BE REVERTED IMMEDIATELY ⚠️**
+ - **Always work on feature branches - NO EXCEPTIONS**
  - Always check the .cursorrules file before starting to ensure you understand the project guidelines
- - Before starting any change or requirement development, first git checkout to main branch, then git pull to get the latest code
- - For each feature or change to be developed, first create a branch, then git checkout to that branch
+ - **MANDATORY workflow for ALL changes:**
+   1. `git checkout main` (switch to main branch)
+   2. `git pull` (get latest changes)
+   3. `git checkout -b feat/your-feature-name` (create and switch to feature branch)
+   4. Make your changes ONLY on the feature branch
+   5. Test thoroughly before committing
+   6. Commit and push to the feature branch
+   7. Create a pull request for code review
  - Use descriptive branch names following the pattern: `feat/feature-name`, `fix/issue-name`, `refactor/component-name`, etc.
+ - **Double-check current branch before ANY commit: `git branch` to ensure you're NOT on main/master**
  - Ensure all changes are made on feature branches and merged through pull requests

+# RustFS Development Guide
+
+## 📋 Code Quality Requirements
+
+### 🔧 Code Formatting Rules
+
+**MANDATORY**: All code must be properly formatted before committing. This project enforces strict formatting standards to maintain code consistency and readability.
+
+#### Pre-commit Requirements
+
+Before every commit, you **MUST**:
+
+1. **Format your code**:
+   ```bash
+   cargo fmt --all
+   ```
+
+2. **Verify formatting**:
+   ```bash
+   cargo fmt --all --check
+   ```
+
+3. **Pass clippy checks**:
+   ```bash
+   cargo clippy --all-targets --all-features -- -D warnings
+   ```
+
+4. **Ensure compilation**:
+   ```bash
+   cargo check --all-targets
+   ```
+
+#### Quick Commands
+
+We provide convenient Makefile targets for common tasks:
+
+```bash
+# Format all code
+make fmt
+
+# Check if code is properly formatted
+make fmt-check
+
+# Run clippy checks
+make clippy
+
+# Run compilation check
+make check
+
+# Run tests
+make test
+
+# Run all pre-commit checks (format + clippy + check + test)
+make pre-commit
+
+# Setup git hooks (one-time setup)
+make setup-hooks
+```
+
+### 🔒 Automated Pre-commit Hooks
+
+This project includes a pre-commit hook that automatically runs before each commit to ensure:
+
+- ✅ Code is properly formatted (`cargo fmt --all --check`)
+- ✅ No clippy warnings (`cargo clippy --all-targets --all-features -- -D warnings`)
+- ✅ Code compiles successfully (`cargo check --all-targets`)
+
+#### Setting Up Pre-commit Hooks
+
+Run this command once after cloning the repository:
+
+```bash
+make setup-hooks
+```
+
+Or manually:
+
+```bash
+chmod +x .git/hooks/pre-commit
+```
+
+### 📝 Formatting Configuration
+
+The project uses the following rustfmt configuration (defined in `rustfmt.toml`):
+
+```toml
+max_width = 130
+fn_call_width = 90
+single_line_let_else_max_width = 100
+```
+
+### 🚫 Commit Prevention
+
+If your code doesn't meet the formatting requirements, the pre-commit hook will:
+
+1. **Block the commit** and show clear error messages
+2. **Provide exact commands** to fix the issues
+3. **Guide you through** the resolution process
+
+Example output when formatting fails:
+
+```
+❌ Code formatting check failed!
+💡 Please run 'cargo fmt --all' to format your code before committing.
+
+🔧 Quick fix:
+   cargo fmt --all
+   git add .
+   git commit
+```
+
+### 🔄 Development Workflow
+
+1. **Make your changes**
+2. **Format your code**: `make fmt` or `cargo fmt --all`
+3. **Run pre-commit checks**: `make pre-commit`
+4. **Commit your changes**: `git commit -m "your message"`
+5. **Push to your branch**: `git push`
+
+### 🛠️ IDE Integration
+
+#### VS Code
+
+Install the `rust-analyzer` extension and add to your `settings.json`:
+
+```json
+{
+    "rust-analyzer.rustfmt.extraArgs": ["--config-path", "./rustfmt.toml"],
+    "editor.formatOnSave": true,
+    "[rust]": {
+        "editor.defaultFormatter": "rust-lang.rust-analyzer"
+    }
+}
+```
+
+#### Other IDEs
+
+Configure your IDE to:
+- Use the project's `rustfmt.toml` configuration
+- Format on save
+- Run clippy checks
+
+### ❗ Important Notes
+
+- **Never bypass formatting checks** - they are there for a reason
+- **All CI/CD pipelines** will also enforce these same checks
+- **Pull requests** will be automatically rejected if formatting checks fail
+- **Consistent formatting** improves code readability and reduces merge conflicts
+
+### 🆘 Troubleshooting
+
+#### Pre-commit hook not running?
+
+```bash
+# Check if hook is executable
+ls -la .git/hooks/pre-commit
+
+# Make it executable if needed
+chmod +x .git/hooks/pre-commit
+```
+
+#### Formatting issues?
+
+```bash
+# Format all code
+cargo fmt --all
+
+# Check specific issues
+cargo fmt --all --check --verbose
+```
+
+#### Clippy issues?
+
+```bash
+# See detailed clippy output
+cargo clippy --all-targets --all-features -- -D warnings
+
+# Fix automatically fixable issues
+cargo clippy --fix --all-targets --all-features
+```
+
+---
+
+Following these guidelines ensures high code quality and smooth collaboration across the RustFS project! 🚀

-/// Reads configuration file content from the storage system
-///
-/// This function reads a specified configuration file through the provided storage API interface

-///
-/// # Parameters
-/// * `api` - An Arc smart pointer containing an implementation of the StorageAPI trait
-/// * `file` - The name of the configuration file to read
-///
-/// # Returns
-/// * `Result<Vec<u8>>` - Returns the configuration file contents as bytes on success, or an error on failure
-///
-/// # Errors
-/// May return the following errors:
-/// * `ConfigError::NotFound` - When the requested configuration file does not exist
-/// * Other storage operation related errors
