Implementations

impl QosService

pub fn new(id: u32) -> Self

pub fn select_and_accumulate_transaction_costs( &self, bank: &Bank, transactions: &[SanitizedTransaction] ) -> (Vec<TransactionCost>, Vec<Result<()>>, usize)

Calculate cost of transactions, determine which ones to include in the slot, and accumulate costs in the cost tracker. Returns a vector of transaction costs, a vector of results indicating which transactions were selected, and the number of transactions that were NOT selected.

pub fn update_or_remove_transaction_costs<'a>( transaction_costs: impl Iterator<Item = &'a TransactionCost>, transaction_qos_results: impl Iterator<Item = &'a Result<()>>, transaction_committed_status: Option<&Vec<CommitTransactionDetails>>, bank: &Arc<Bank> )

Update the transaction cost in the cost_tracker with the real cost for transactions that were executed successfully; Otherwise remove the cost from the cost tracker, therefore preventing cost_tracker being inflated with unsuccessfully executed transactions.

pub fn report_metrics(&self, bank: Arc<Bank>)

pub fn accumulate_actual_execute_cu(&self, units: u64)

pub fn accumulate_actual_execute_time(&self, micro_sec: u64)
