Struct CostPredictionRecord 

pub struct CostPredictionRecord {
    pub wcoj_cost: f64,
    pub hash_cost: f64,
}

Cost evidence carried with a planned WCOJ-vs-hash route.

Fields

wcoj_cost: f64

Estimated WCOJ work under the selected plan.

hash_cost: f64

Estimated hash-chain work under the captured fallback plan.

Implementations

impl CostPredictionRecord

pub fn empty() -> Self

Stable evidence for incomplete stats: hash is the safe default route.

Trait Implementations

impl Clone for CostPredictionRecord

fn clone(&self) -> CostPredictionRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CostPredictionRecord

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

Formats the value using the given formatter.

impl PartialEq for CostPredictionRecord

fn eq(&self, other: &CostPredictionRecord) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
