teddyjfpender Cairo Storage Optimization
Overview
Show how to reduce storage costs by packing multiple values into one slot and manipulating bits safely.
Quick Use
- Read
references/storage-optimization.mdbefore answering. - Use shift and mask operations with
core::integer::bitwiseor arithmetic. - Mention StorePacking for automatic packing where appropriate.
Response Checklist
- Ensure packed values fit within 251 bits total.
- Use explicit masks and shifts for extraction.
- Consider a custom struct with StorePacking for reusable packing logic.
