Fields

total_tx_size: u64

| sum of all mempool tx’s virtual sizes. | Differs from serialized tx size since | witness data is discounted. Defined | in BIP 141. |

total_fee: Amount

| sum of all mempool tx’s fees (NOT modified | fee) |

cached_inner_usage: u64

| sum of dynamic memory usage of all the | map elements (NOT the maps themselves) |

last_rolling_fee_update: Arc<Mutex<i64>>

block_since_last_rolling_fee_bump: AtomicBool

rolling_minimum_fee_rate: AtomicF64

| minimum fee to get into the pool, decreases | exponentially |

epoch: Arc<Mutex<Epoch>>

sequence_number: RefCell<u64>

| In-memory counter for external mempool | tracking purposes. | | This number is incremented once every time | a transaction is added or removed from the | mempool for any reason.

is_loaded: bool

map_tx: TxMemPoolIndexedTransactionSet

tx_hashes: Vec<(u256, TxMemPoolTxIter)>

| All tx witness hashes/entries in mapTx, | in random order |

unbroadcast_txids: HashSet<u256>

| Track locally submitted transactions | to periodically retry initial broadcast. |

map_next_tx: IndirectMap<OutPoint, Arc<Transaction>>

map_deltas: HashMap<u256, Amount>
