transactionOutputStatus Source #
Arguments
| :: BlockNumber |
Current block number for inspecting the state of the transaction output |
| -> TxIdState |
Information on the state of a transaction. Needed for determining its status. |
| -> TxOutBalance |
Balance of spent and unspent transaction outputs. |
| -> TxOutRef |
Target transaction output for inspecting its state. |
| -> Either TxStatusFailure TxOutStatus |
Given the current block, compute the status for the given transaction output by getting the state of the transaction that produced it and checking if the output is spent or unspent.
fromTx :: ChainIndexTx -> TxOutBalance Source #
isUnspentOutput :: TxOutRef -> UtxoState TxOutBalance -> Bool Source #
Whether a
TxOutRef
is a member of the UTXO set (ie. unspent)
unspentOutputs :: UtxoState TxOutBalance -> Set TxOutRef Source #
The UTXO set
isSpentOutput :: TxOutRef -> UtxoState TxOutBalance -> Bool Source #
Whether a
TxOutRef
is a member of the spent tx output set.
spentOutputs :: UtxoState TxOutBalance -> Set TxOutRef Source #
The spent output set
fromBlock :: Tip -> [ ChainIndexTx ] -> UtxoState TxOutBalance Source #
UtxoIndex
for a single block
rollback :: Point -> UtxoIndex TxOutBalance -> Either RollbackFailed ( RollbackResult TxOutBalance ) Source #
Perform a rollback on the utxo index
