Struct AppraisalOutput

Source 
pub struct AppraisalOutput {
    pub asset: AssetRef,
    pub capacity: Capacity,
    pub unmet_demand: IndexMap<TimeSliceID, Flow>,
    pub metric: f64,

Expand description

The output of investment appraisal required to compare potential investment decisions

Fields§

§asset: AssetRef

The asset being appraised

§capacity: Capacity

The hypothetical capacity to install

§unmet_demand: IndexMap<TimeSliceID, Flow>

The hypothetical unmet demand following investment in this asset

§metric: f64

The comparison metric to compare investment decisions (lower is better)

Implementations§

Source§

impl AppraisalOutput

Source

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 (as determined by the [approx_eq!] macro) 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.
