State Reads/Writes
State Reads and Writes from objects may be only be done by the current actor using the following system calls:
actor_open_fieldactor_open_key_value_entryactor_index_insertactor_index_removeactor_index_scan_keysactor_index_drainactor_sorted_index_insertactor_sorted_index_removeactor_sorted_index_scan
Key Value Stores are a special type of object though which may be read/written to as long as one has a reference to that key value store. This is accessible via the system call:
key_value_store_open_entry
