Struct AppraisalOutput 

pub struct AppraisalOutput {
    pub asset: AssetRef,
    pub activity: IndexMap<TimeSliceID, Activity>,
    pub unmet_demand: DemandMap,
    pub metric: Option<Box<dyn MetricTrait>>,
    pub coefficients: Rc<ObjectiveCoefficients>,
}

The output of investment appraisal required to compare potential investment decisions

Fields

asset: AssetRef

The asset being appraised

activity: IndexMap<TimeSliceID, Activity>

Time slice level activity of the asset

unmet_demand: DemandMap

The hypothetical unmet demand following investment in this asset

metric: Option<Box<dyn MetricTrait>>

The comparison metric to compare investment decisions

coefficients: Rc<ObjectiveCoefficients>

Activity coefficients and market costs used in the appraisal

Implementations

impl AppraisalOutput

fn new<T: MetricTrait>( asset: AssetRef, results: ResultsMap, metric: Option<T>, coefficients: Rc<ObjectiveCoefficients>, ) -> Self

Create a new AppraisalOutput

pub fn compare_metric(&self, other: &Self) -> Ordering

Compare this appraisal to another on the basis of the comparison metric.

Note that if the metrics are approximately equal, then Ordering::Equal is returned. The reason for this is because different CPU architectures may lead to subtly different values for the comparison metrics and if the value is very similar to another, then it can lead to different decisions being made, depending on the user’s platform (e.g. macOS ARM vs. Windows). We want to avoid this, if possible, which is why we use a more approximate comparison.
