Module rgbstd::persistence

Module defines API used by providers of persistent data for RGB contracts.

These data include:

1. Stash: a consensus-critical data for client-side-validation which must be preserved and backed up.
2. rgb::ContractState, updated with each enclosed consignment and disclosure.
3. Index over stash, which simplifies construction of a new consignments.
4. Inventory, which abstracts stash, contract states and index for complex operations requiring participation of all of them.

2-4 data can be re-computed from the stash in case of loss or corruption.
