Performance by Design

Rust's Zero-Cost Abstractions: Maximum performance, minimal overhead
Efficient Rendering: Virtual DOM with smart diffing
Lazy Loading: Components and data loaded on demand
Memory Safety: No garbage collection pauses or memory leaks

Maintainable Architecture

Type Safety: Compile-time error prevention
Modular Design: Clear separation of concerns
Test Coverage: Unit, integration, and UI tests
Documentation: Comprehensive inline and external docs

🤝 Contributing

Test subsets (CI-friendly):
- Fast local default: run cargo test (only non-ignored tests).
- Mark slow/integration/system tests with #[ignore] or #[ignore = "slow"] so they don’t run locally by default.
- CI slow suite: run cargo test -- --ignored to execute ignored tests in pipelines.
- Feature-gated integration tests: wrap with #[cfg(feature = "integration")] and run with cargo test --features integration when needed.
- Filter by module to iterate faster: cargo test ingest::, cargo test nlp::, cargo test planner::, etc.

I welcome contributions! Here's how to get involved:

Priority Areas

Interactive Features: Help implement progress tracking and note-taking
UI/UX Polish: Improve animations, transitions, and micro-interactions
Platform Integration: Better OS integration (notifications, shortcuts)
Import Sources: Add support for new platforms (Udemy, Coursera, etc.)
Export Formats: Additional study guide formats and templates

Contribution Process

Check Issues: Look for "good first issue" or "help wanted" labels
Fork & Branch: Create a feature branch from main
Develop: Implement with tests and documentation
Test: Ensure all tests pass (cargo test)
Submit PR: Include description and link to related issues

Code Standards

Rust Idioms: Follow official Rust style guidelines
Error Handling: Use thiserror for custom errors, anyhow for applications
