## Unique Features (Not in Other Crates)
The `gap_validation` module provides features not found in other Rust calendar crates:
1. **Gap Detection** - Find free time between events
2. **Overlap Detection** - Identify scheduling conflicts
3. **Schedule Density** - Calculate occupancy metrics
4. **Available Slots** - Find times that fit specific durations
5. **Slot Availability** - Check if a specific time is free
6. **Conflict Resolution** - Suggest alternative times for conflicts
7. **Longest Gap Finder** - Find maximum continuous free time

## Test-Driven Development
The project was developed using TDD:
1. Tests written before implementation
2. Implementation driven by test requirements
3. Refactoring validated by tests
4. Edge cases identified through test exploration
## Future Test Enhancements
Potential areas for additional testing:
- [ ] ICS import integration tests
- [ ] Performance benchmarks for large calendars
- [ ] Fuzzing for recurrence edge cases
- [ ] Property-based testing with proptest
- [ ] Multi-threaded access patterns
