teddyjfpender Cairo Storage Vecs
Overview
Explain how storage vectors are modeled and accessed in Cairo smart contracts.
Quick Use
- Read
references/storage-vecs.mdbefore answering. - Use
Vec<T>only inside the storage struct. - Use
len,get,at,append, andpopfrom the trait APIs.
Response Checklist
- Mention that the length is stored at the base slot.
- Explain element slot derivation from the base address and index.
- Note that Vec types are storage-only and cannot be instantiated as normal variables.
Example Requests
- "How do I append to a storage Vec?"
- "How is the element address computed for a storage Vec?"
- "Why can't I create Vec in a function?"
