## API Design Principles
### Consistency
- Repository-centric design: operations as methods on `Repository`
- Consistent error handling with `Result<T, GitError>`
- Type-safe enums for status, branch types, etc.
- Builder patterns for complex operations with options
### Performance
- Lazy evaluation where possible
- Streaming for large operations
- Progress callbacks for long-running operations
- Efficient caching of git command results
### Ergonomics
- Sensible defaults for common use cases
- Method chaining where appropriate
- Clear, descriptive method names
- Comprehensive documentation with examples
## Quality Standards
### Testing
- Unit tests for all public APIs
- Integration tests with real git repositories
- Cross-platform testing (Windows, macOS, Linux)
- Performance benchmarks for critical operations
### Documentation
- Comprehensive rustdoc for all public APIs
- Example code in documentation
- Example programs in `examples/` directory
- Clear error messages and recovery suggestions
### Compatibility
- Support latest stable Rust (currently 1.89+)
- Cross-platform file path handling
- Graceful handling of different git versions
- Consistent behavior across operating systems
## Implementation Notes
### Technical Decisions
- Continue using `std::process::Command` for git operations
- Maintain clean separation between core types and command modules
- Use `PathBuf` for all path operations for cross-platform compatibility
- Implement `From` traits for ergonomic type conversions
### Breaking Changes
- Follow semantic versioning strictly
- Deprecate before removing APIs
- Provide migration guides for major version updates
- Maintain backwards compatibility within major versions
## Success Metrics
### Adoption
- Crates.io download counts
- GitHub stars and forks
- Community contributions and issues
- Integration in other Rust projects
### Quality
- Test coverage > 90%
- Documentation coverage 100%
- Zero clippy warnings
- Fast CI/CD pipeline (< 5 minutes)
