func (*BoltDB) SaveKeyset 

func (db *BoltDB) SaveKeyset(keyset *crypto.WalletKeyset) error

NOTE: Keysets are stored in nested buckets by mint URL. I.e a keyset with mint URL http://mint.com will create a bucket inside the KEYSETS_BUCKET named by the mint URL and inside this bucket, save the keysets by keyset id

func (*BoltDB) SaveMeltQuote 

func (db *BoltDB) SaveMeltQuote(quote MeltQuote) error

func (*BoltDB) UpdateKeysetMintURL 

func (db *BoltDB) UpdateKeysetMintURL(oldURL, newURL string) error

UpdateKeysetMintURL creates a new bucket named with newURL. It will then iterate over all the keysets that were stored in the oldURL bucket and copy them over to the new bucket with newURL. It also needs to change the MintURL field for each keyset.
