Stores up to MAX_NUM_RECENT_BLOCKS recent block’s prioritization fee, A separate internal thread service_thread handles additional tasks when a bank is frozen, and collecting stats and reporting metrics.

Implementations

impl PrioritizationFeeCache

pub fn new(capacity: u64) -> Self

pub fn update<'a>( &self, bank: Arc<Bank>, txs: impl Iterator<Item = &'a SanitizedTransaction> )

Update with a list of transactions’ tx_priority_details and tx_account_locks; Only transactions have both valid priority_detail and account_locks will be used to update fee_cache asynchronously.

pub fn finalize_priority_fee(&self, slot: Slot)

Finalize prioritization fee when it’s bank is completely replayed from blockstore, by pruning irrelevant accounts to save space, and marking its availability for queries.

pub fn available_block_count(&self) -> usize

Returns number of blocks that have finalized minimum fees collection

pub fn get_prioritization_fees( &self, account_keys: &[Pubkey] ) -> HashMap<Slot, u64>
