Struct ScoreChange 

#[non_exhaustive]
pub struct ScoreChange {
    pub a: Option<f64>,
    pub b: Option<f64>,
    pub abs: Option<f64>,
    pub rel_pct: Option<f64>,
    pub evidence: Sides<Evidence>,
}

One score on both sides and how it moved.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

a: Option<f64>

The score in a, or None when a did not assess it.

b: Option<f64>

The score in b, or None when b did not assess it.

abs: Option<f64>

b - a in score points, when both sides have a score.

rel_pct: Option<f64>

b - a as a percentage of a, when both have a score and a is not zero.

evidence: Sides<Evidence>

The evidence behind each side’s score: the scan’s coverage, and whether the score was computed from a retained sample of the rows.
