Struct WeightedAverageBackupAccumulator 

Source 
struct WeightedAverageBackupAccumulator<W: UnitType> {
    primary: WeightedAverageAccumulator<W>,
    backup: WeightedAverageAccumulator<W>,
}
Expand description

Weighted average accumulator with a backup weighting path for MoneyPerFlow prices.

Fields§

§primary: WeightedAverageAccumulator<W>

Primary weighted average path.

§backup: WeightedAverageAccumulator<W>

Backup weighted average path.

Implementations§

Source§

impl<W: UnitType> WeightedAverageBackupAccumulator<W>

Source

fn add(&mut self, value: MoneyPerFlow, weight: W, backup_weight: W)

Add a weighted value to the accumulator with a backup weight.

Source

fn finalise(self) -> Option<MoneyPerFlow>

Solve the weighted average, falling back to backup weights if needed.

Returns None if both denominators are zero (or close to zero).
