The Big Picture
Multi-layer bitmap enables O(log n) tick traversal.
Use Cases
- Optimize swap path finding
From Chain Metadata
Tick index bitmap words storage
Purpose & Usage
Purpose
Efficient lookup of next tick during swaps.
Common Query Patterns
- Query by (netuid, layer, word)
Query Keys
| # | Name | Type | Description |
|---|---|---|---|
| 1 | key1 | u16 | key1 (u16) |
| 2 | key2 | LayerLevel | key2 (LayerLevel) |
| 3 | key3 | u32 | key3 (u32) |
