Implementations

impl MemPoolAccept

pub fn new(mempool: &mut TxMemPool, active_chainstate: &mut ChainState) -> Self

pub fn check_fee_rate( &mut self, package_size: usize, package_fee: Amount, state: &mut TxValidationState ) -> bool

| Compare a package’s feerate against | minimum allowed. |

pub fn pre_checks( &mut self, args: &mut MemPoolAcceptATMPArgs, ws: &mut MemPoolAcceptWorkspace ) -> bool

| Run the policy checks on a given | transaction, excluding any script checks. | | Looks up inputs, calculates feerate, | considers replacement, evaluates package | limits, etc. As this function can be | invoked for “free” by a peer, only tests | that are fast should be done here (to avoid | CPU DoS).

pub fn policy_script_checks( &mut self, args: &MemPoolAcceptATMPArgs, ws: &mut MemPoolAcceptWorkspace, txdata: &mut PrecomputedTransactionData ) -> bool

| Run the script checks using our policy | flags. As this can be slow, we should only | invoke this on transactions that have | otherwise passed policy checks.

pub fn consensus_script_checks( &mut self, args: &MemPoolAcceptATMPArgs, ws: &mut MemPoolAcceptWorkspace, txdata: &mut PrecomputedTransactionData ) -> bool

| Re-run the script checks, using consensus | flags, and try to cache the result in the | scriptcache. This should be done after | PolicyScriptChecks(). This requires that | all inputs either be in our utxo set or in | the mempool.

pub fn finalize( &mut self, args: &MemPoolAcceptATMPArgs, ws: &mut MemPoolAcceptWorkspace ) -> bool

| Try to add the transaction to the mempool, | removing any conflicts first. | | Returns true if the transaction is in the | mempool after any size limiting is | performed, false otherwise.

pub fn accept_single_transaction( &mut self, ptx: &TransactionRef, args: &mut MemPoolAcceptATMPArgs ) -> MempoolAcceptResult

| Single transaction acceptance |

pub fn accept_multiple_transactions( &mut self, txns: &Vec<TransactionRef>, args: &mut MemPoolAcceptATMPArgs ) -> PackageMempoolAcceptResult

| Multiple transaction acceptance. | Transactions may or may not be interdependent, | but must not conflict with each other. | Parents must come before children if | any dependencies exist. |
