- `bid_price(&self) -> f64`
- `ask_price(&self) -> f64`
- `is_valid(&self) -> bool`
- `empty() -> Self`

### Mbp10Snapshot

## Performance Quick Reference

| Operation | Time | Throughput |
|-----------|------|-----------|
| `mid_price()` | <100ns | 10M/sec |
| `spread()` | <100ns | 10M/sec |
| `volume_imbalance()` | ~500ns | 2M/sec |
| `calculate_vwap()` | ~1.2μs | 0.8M/sec |
| Extract 51 features | 5-10μs | 100-200K/sec |
| Update level | <200ns | 5M/sec |

**Real-time Throughput**: 50K+ feature vectors/second
