# Ferrous DI - Gold Standard Repository Roadmap
This document outlines the plan to elevate ferrous-di to a gold standard Rust repository with excellent code organization, tooling, and community infrastructure.
## Phase 1: Code Organization & Refactoring 🏗️
**Goal:** Transform monolithic lib.rs into well-organized modules
### Module Structure
```
src/
├── lib.rs # Public API exports only
├── error.rs # DiError and Result types
├── lifetime.rs # Lifetime enum
├── key.rs # Key enum and related logic
├── registration.rs # Registration struct
├── collection/
│ ├── mod.rs # ServiceCollection implementation
│ ├── builder.rs # Builder pattern for ServiceCollection
│ └── descriptors.rs # ServiceDescriptor functionality
├── provider/
│ ├── mod.rs # ServiceProvider implementation
│ ├── resolver.rs # Resolver and ResolverContext
│ └── scope.rs # Scope and ScopedResolver
├── options/
│ ├── mod.rs # Options<T> and IOptions trait
│ └── builder.rs # OptionsBuilder implementation
└── traits/
├── mod.rs # Trait exports
├── dispose.rs # Dispose and AsyncDispose traits
└── resolver.rs # Resolver trait
```
### Refactoring Steps
- [ ] Create module structure
- [ ] Extract error types to error.rs
- [ ] Move Key logic to key.rs
- [ ] Extract ServiceCollection to collection module
- [ ] Extract ServiceProvider to provider module
- [ ] Extract Options pattern to options module
- [ ] Move traits to traits module
- [ ] Update all imports and exports
- [ ] Ensure all tests still pass
## Phase 2: CI/CD Infrastructure 🚀
**Goal:** Automated testing, building, and deployment
### GitHub Actions Workflows
- [ ] `.github/workflows/ci.yml` - Test matrix (stable, beta, nightly)
- [ ] `.github/workflows/coverage.yml` - Code coverage with tarpaulin
- [ ] `.github/workflows/benchmarks.yml` - Performance regression detection
- [ ] `.github/workflows/release.yml` - Automated publishing
- [ ] `.github/workflows/audit.yml` - Security and license scanning
### CI Configuration
```yaml
# Test on multiple Rust versions and OS
matrix:
rust: [stable, beta, nightly]
os: [ubuntu-latest, macos-latest, windows-latest]
```
## Phase 3: Documentation Enhancement 📚
**Goal:** Comprehensive documentation for all audiences
### Documentation Files

## Phase 4: Development Tools 🔧
**Goal:** Consistent code quality and developer experience
### Configuration Files
- [ ] `rustfmt.toml` - Code formatting rules
- [ ] `clippy.toml` - Linting configuration

- [ ] `.pre-commit-config.yaml` - Git hooks
### Tool Configuration
```toml
# rustfmt.toml
edition = "2021"
max_width = 100
use_small_heuristics = "Max"
imports_granularity = "Module"
# clippy.toml
avoid-breaking-exported-api = true
msrv = "1.70.0"
```
## Phase 5: Testing Improvements 🧪
**Goal:** Comprehensive test coverage with multiple strategies
### Testing Enhancements
- [ ] Add property-based tests with proptest
- [ ] Add fuzzing with cargo-fuzz
- [ ] Create integration test suite

### Test Organization
```
tests/
├── integration/
│ ├── full_application.rs
│ ├── concurrent_access.rs
│ └── memory_leaks.rs
├── property/
│ ├── registration_props.rs
│ └── resolution_props.rs
└── benchmarks/
└── regression.rs
```
## Phase 6: API Polish 🎯
**Goal:** Ergonomic and powerful API
### API Improvements
- [ ] Derive macros for common patterns
- [ ] Builder pattern for ServiceCollection
- [ ] Extension traits for common use cases
- [ ] Feature flags for optional functionality
- [ ] Consider no_std support
### Feature Flags
```toml
[features]
default = ["std"]
std = []
derive = ["ferrous-di-derive"]
tokio = ["dep:tokio"]
async-std = ["dep:async-std"]
tracing = ["dep:tracing"]
```
