Types ¶
type DB ¶
type DB struct {
// contains filtered or unexported fields
}
DB encapsulates a leveldb.DB storage
func (*DB) FetchBalance ¶
FetchBalance calculates the balance
func (*DB) FetchInputs ¶
FetchInputs fetches transaction inputs amounting to the specified amount. Inputs are decrypted using a decryption key (view key)
func (*DB) FetchTxRecords ¶
FetchTxRecords transaction records
func (*DB) GetWalletHeight ¶
GetWalletHeight returns the height of the blockchain known to the wallet
func (*DB) PutInput ¶
func (db *DB) PutInput(encryptionKey []byte, pubkey ristretto.Point, amount, mask, privKey ristretto.Scalar, unlockHeight uint64) error
PutInput inserts a UTXO input (i.e. a Ristretto point) in the DB
func (*DB) PutKeyImage ¶
PutKeyImage saves the transaction's key image used to prevent double spending
func (*DB) PutTxRecord ¶
func (db *DB) PutTxRecord(tx transactions.Transaction, direction txrecords.Direction, privView *key.PrivateView) error
PutTxRecord saves the transaction record on the DB
func (*DB) RemoveInput ¶
RemoveInput removes a UTXO input from the DB
func (*DB) UpdateLockedInputs ¶
UpdateLockedInputs will set the lockheight for an input to 0 if the given `height` is greater or equal than the input lockheight, signifying that this input is unlocked.
func (*DB) UpdateWalletHeight ¶
UpdateWalletHeight updates the wallet height
