How to iterate over PersistentVector
This page in NEAR docs explains how all of the collections work and their features
https://docs.near.org/docs/concepts/data-storage
With PersistentVector you can
- use
lengthas a bound on a loop - use
pop(or its aliaspopBack) to move incrementally
In general, all of these collections are just wrappers for the key-value store which means you can write your own.
If you can imagine a missing data structure, we're almost certainly happy to fund you building one. Check out https://near.university/teach for opportunities to contribute through grants, fellowships and more
