Transaction pool configuration

Fields

max_tx_pool_size: usize

Keep the transaction pool below <max_tx_pool_size> mb

min_fee_rate: FeeRate

txs with lower fee rate than this will not be relayed or be mined

min_rbf_rate: FeeRate

txs need to pay larger fee rate than this for RBF

max_tx_verify_cycles: Cycle

tx pool rejects txs that cycles greater than max_tx_verify_cycles

max_ancestors_count: usize

max ancestors size limit for a single tx

keep_rejected_tx_hashes_days: u8

rejected tx time to live by days

keep_rejected_tx_hashes_count: u64

rejected tx count limit

persisted_data: PathBuf

The file to persist the tx pool on the disk when tx pool have been shutdown.

By default, it is a subdirectory of ‘tx-pool’ subdirectory under the data directory.

recent_reject: PathBuf

The recent reject record database directory path.

By default, it is a subdirectory of ‘tx-pool’ subdirectory under the data directory.

expiry_hours: u8

The expiration time for pool transactions in hours

Implementations

impl TxPoolConfig

pub fn adjust<P: AsRef<Path>>(&mut self, root_dir: &Path, tx_pool_dir: P)

Canonicalizes paths in the config options.

If self.persisted_data is not set, set it to data_dir / tx_pool_persisted_data.

If self.path is relative, convert them to absolute path using root_dir as current working directory.

Trait Implementations

impl Clone for TxPoolConfig

fn clone(&self) -> TxPoolConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TxPoolConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TxPoolConfig

fn default() -> Self

Returns the “default value” for a type.

impl Serialize for TxPoolConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
