Struct ValidationLatencyEstimator 

Source 
pub struct ValidationLatencyEstimator {
    sample_window: Vec<(u64, ValidationLatencySample)>,
    elapsed_counts: BTreeMap<Duration, usize>,
    gas_used_counts: BTreeMap<u64, usize>,
    transaction_count_counts: BTreeMap<usize, usize>,
}
Expand description

Tracks recent local execution-layer block validation latency.

The validation latency estimate uses the recent P90 successful proposal validation as an absolute floor, then scales that floor up when the current workload exceeds the recent P90 gas or transaction count. This avoids combining independent per-unit rates from different workloads while still reserving validator headroom when the builder grows beyond the workloads that produced the feedback.

Fields§

§sample_window: Vec<(u64, ValidationLatencySample)>

Samples are kept in id order for retention; count maps are keyed by observed values so estimate snapshots can read percentiles without sorting.

§elapsed_counts: BTreeMap<Duration, usize>§gas_used_counts: BTreeMap<u64, usize>§transaction_count_counts: BTreeMap<usize, usize>

Implementations§

Source§

impl ValidationLatencyEstimator

Source

fn insert_sample_counts(&mut self, sample: ValidationLatencySample)

Source

fn remove_sample_counts(&mut self, sample: ValidationLatencySample)

Source

fn insert_sample(&mut self, sample_id: u64, sample: ValidationLatencySample)

Source

pub fn observe( &mut self, sample_id: u64, workload: ValidationLatencyWorkload, elapsed: Duration, )

Records local time spent validating a block through the execution layer.

Source

pub fn estimate(&self) -> Option<ValidationLatencyEstimate>

Returns the current estimate for execution-layer block validation work.

None means this node has not yet observed any successful validations. Callers should fall back to their conservative validator-work estimate in that case.
