Module capsules

Functions

• copy
  Copies a number of contiguous entries in the per-contract non-volatile database. This allows for efficient data structures by avoiding repeated calls to loadCapsule and storeCapsule. Supports overlapping source and destination regions (which will result in the overlapped source values being overwritten). All copied slots must exist in the database (i.e. have been stored and not deleted)
• delete
  Deletes data in the per-contract non-volatile database. Does nothing if no data was present.
• load
  Returns data previously stored via storeCapsule in the per-contract non-volatile database. Returns Option::none() if nothing was stored at the given slot.
• store
  Stores arbitrary information in a per-contract non-volatile database, which can later be retrieved with load. If data was already stored at this slot, it is overwritten.
