Hello! Would you know if it is possible for a contract to read the storage of another contract, e.g. a storage_mapper, even if it is not preceeded by the tag #view or #endpoint?
There is no "friendly" API for it, but it's possible. You'll probably have to integrate the low-level function yourself, as I don't think this specific API is available to the SC trait.
