The service binary lives in `rustfs/` with entrypoints under `src/main.rs`. Crypto, IAM, and KMS components sit in `crates/` (notably `crates/crypto`, `crates/iam`, `crates/kms`). End-to-end fixtures are in `crates/e2e_test/` and `test_standalone/`. Operational tooling resides in `scripts/`, while deployment manifests are under `deploy/` and Docker assets at the root.

Cross-platform builds rely on `./build-rustfs.sh --platform ` or `make build-cross-all`. Validate code early with `cargo check --all-targets`. Run unit coverage using `cargo test --workspace --exclude e2e_test` and prefer `cargo nextest run --all --exclude e2e_test` if installed.

The project adopts a modular architecture, supporting erasure coding storage, multi-tenant management, observability, and other enterprise-level features. - -## Core Architecture Principles - -### 1. Modular Design - -- Project uses Cargo workspace structure, containing multiple independent crates -- Core modules: `rustfs` (main service), `ecstore` (erasure coding storage), `common` (shared components) -- Functional modules: `iam` (identity management), `madmin` (management interface), `crypto` (encryption), etc. -- Tool modules: `cli` (command line tool), `crates/*` (utility libraries) - -### 2. Asynchronous Programming Pattern - -- Comprehensive use of `tokio` async runtime -- Prioritize `async/await` syntax -- Use `async-trait` for async methods in traits -- Avoid blocking operations, use `spawn_blocking` when necessary - -### 3. Error Handling Strategy - -- **Use modular, type-safe error handling with `thiserror`** -- Each module should define its own error type using `thiserror::Error` derive macro -- Support error chains and context information through `#[from]` and `#[source]` attributes -- Use `Result` type aliases for consistency within each module -- Error conversion between modules should use explicit `From` implementations -- Follow the pattern: `pub type Result = core::result::Result` -- Use `#[error("description")]` attributes for clear error messages -- Support error downcasting when needed through `other()` helper methods -- Implement `Clone` for errors when required by the domain logic - -## Code Style Guidelines - -### 1. Formatting Configuration - -```toml -max_width = 130 -fn_call_width = 90 -single_line_let_else_max_width = 100 -``` - -### 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 -``` - -### 3. Naming Conventions - -- Use `snake_case` for functions, variables, modules -- Use `PascalCase` for types, traits, enums -- Constants use `SCREAMING_SNAKE_CASE` -- Global variables prefix `GLOBAL_`, e.g., `GLOBAL_Endpoints` -- Use meaningful and descriptive names for variables, functions, and methods -- Avoid meaningless names like `temp`, `data`, `foo`, `bar`, `test123` -- Choose names that clearly express the purpose and intent - -### 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 - -### 5. Documentation Comments - -- Public APIs must have documentation comments -- Use `///` for documentation comments -- Complex functions add `# Examples` and `# Parameters` descriptions -- Error cases use `# Errors` descriptions -- Always use English for all comments and documentation -- Avoid meaningless comments like "debug 111" or placeholder text - -### 6. Import Guidelines - -- Standard library imports first -- Third-party crate imports in the middle -- Project internal imports last -- Group `use` statements with blank lines between groups - -## Asynchronous Programming Guidelines - -- Comprehensive use of `tokio` async runtime -- Prioritize `async/await` syntax -- Use `async-trait` for async methods in traits -- Avoid blocking operations, use `spawn_blocking` when necessary -- Use `Arc` and `Mutex`/`RwLock` for shared state management -- Prioritize async locks from `tokio::sync` -- Avoid holding locks for long periods - -## Logging and Tracing Guidelines - -- Use `#[tracing::instrument(skip(self, data))]` for function tracing -- Log levels: `error!` (system errors), `warn!` (warnings), `info!` (business info), `debug!` (development), `trace!` (detailed paths) -- Use structured logging with key-value pairs for better observability - -## Error Handling Guidelines - -- Use `thiserror` for module-specific error types -- Support error chains and context information through `#[from]` and `#[source]` attributes -- Use `Result` type aliases for consistency within each module -- Error conversion between modules should use explicit `From` implementations -- Follow the pattern: `pub type Result = core::result::Result` -- Use `#[error("description")]` attributes for clear error messages -- Support error downcasting when needed through `other()` helper methods -- Implement `Clone` for errors when required by the domain logic - -## Performance Optimization Guidelines - -- Use `Bytes` instead of `Vec` for zero-copy operations -- Avoid unnecessary cloning, use reference passing -- Use `Arc` for sharing large objects -- Use `join_all` for concurrent operations -- Use `LazyLock` for global caching -- Implement LRU cache to avoid memory leaks +## Coding Style & Naming Conventions +Formatting follows `rustfmt.toml` (130-column width, async-friendly wrapping). Adopt `snake_case` for items, `PascalCase` for types, and `SCREAMING_SNAKE_CASE` for constants. Avoid `unwrap()` and `expect()` outside tests; propagate errors with `Result` and crate-specific `thiserror` types. Keep async code non-blocking—use `tokio::task::spawn_blocking` if CPU-heavy work is unavoidable. Document public APIs with focused `///` comments that cover parameters, errors, and examples. ## Testing Guidelines +Co-locate unit tests with modules and use behavior-led names such as `handles_expired_token`. Place integration suites in `tests/` folders and exhaustive flows in `crates/e2e_test/`. For KMS validation, clear proxies and run `NO_PROXY=127.0.0.1,localhost HTTP_PROXY= HTTPS_PROXY= cargo test --package e2e_test kms:: -- --nocapture --test-threads=1`. Always finish by running `cargo test --all` to ensure coverage across crates. -- Write meaningful test cases that verify actual functionality -- Avoid placeholder or debug content like "debug 111", "test test", etc. -- Use descriptive test names that clearly indicate what is being tested -- Each test should have a clear purpose and verify specific behavior -- Test data should be realistic and representative of actual use cases -- Use `e2e_test` module for end-to-end testing -- Simulate real storage environments +## Commit & Pull Request Guidelines +Create feature branches (`feat/...`, `fix/...`, `refactor/...`) after syncing `main`; never commit directly to the protected branch. Commits must align with Conventional Commits (e.g., `feat: add kms key rotation`) and remain under 72 characters. Each commit should compile, format cleanly, pass clippy with `-D warnings`, and include relevant tests. Open pull requests with `gh pr create`, provide a concise summary, list verification commands, and wait for reviewer approval before merging. -## Cross-Platform Compatibility Guidelines - -- **Always consider multi-platform and different CPU architecture compatibility** when writing code -- Support major architectures: x86_64, aarch64 (ARM64), and other target platforms -- Use conditional compilation for architecture-specific code -- Use feature flags for platform-specific dependencies -- Provide fallback implementations for unsupported platforms -- Test on multiple architectures in CI/CD pipeline -- Use explicit byte order conversion when dealing with binary data -- Prefer `to_le_bytes()`, `from_le_bytes()` for consistent little-endian format -- Use portable SIMD libraries like `wide` or `packed_simd` -- Provide fallback implementations for non-SIMD architectures - -## Security Guidelines - -- Disable `unsafe` code (workspace.lints.rust.unsafe_code = "deny") -- Use `rustls` instead of `openssl` -- Use IAM system for permission checks -- Validate input parameters properly -- Implement appropriate permission checks -- Avoid information leakage - -## Configuration Management Guidelines - -- Use `RUSTFS_` prefix for environment variables -- Support both configuration files and environment variables -- Provide reasonable default values -- Use `serde` for configuration serialization/deserialization - -## Dependency Management Guidelines - -- Manage versions uniformly at workspace level -- Use `workspace = true` to inherit configuration -- Use feature flags for optional dependencies -- Don't introduce new tools without strong justification - -## Deployment and Operations Guidelines - -- Provide Dockerfile and docker-compose configuration -- Support multi-stage builds to optimize image size -- Integrate OpenTelemetry for distributed tracing -- Support Prometheus metrics collection -- Provide Grafana dashboards -- Implement health check endpoints - -## Code Review Checklist - -### 1. **Code Formatting and Quality (MANDATORY)** - -- [ ] **Code is properly formatted** (`cargo fmt --all --check` passes) -- [ ] **All clippy warnings are resolved** (`cargo clippy --all-targets --all-features -- -D warnings` passes) -- [ ] **Code compiles successfully** (`cargo check --all-targets` passes) -- [ ] **Pre-commit hooks are working** and all checks pass -- [ ] **No formatting-related changes** mixed with functional changes (separate commits) - -### 2.
