) -> StdResult<()>
Expand description

stores ownership history for a given token_id. Meant to be used for nfts. In base specification, only the latest (ie: current) owner is relevant. But
this design pattern is used to allow viewing a token_id’s ownership history, which is allowed in the additional specifications
