Struct GradientRule 

pub struct GradientRule {
    pub minpoint: Option<InterpolationPoint>,
    pub midpoint: Option<InterpolationPoint>,
    pub maxpoint: Option<InterpolationPoint>,
}

GradientRule — a color scale of two or three InterpolationPoints. midpoint absent means a plain two-color scale.

A documented cut (issue #1793), mirroring validation.rs’s “curate rather than chase every enum value” stance: the endpoints this crate builds are always anchored MIN/MAX. Sheets also allows an endpoint to be anchored at an explicit NUMBER/PERCENT/PERCENTILE value, which this crate doesn’t build — docs/drive.md names this gap — but reads back from a rule made in the Sheets UI.

Every point is optional, as in the API: this crate always sets minpoint/maxpoint when building a rule, and never sends back a rule it read, so the optionality only makes reads tolerant (issue #1944).

Fields

minpoint: Option<InterpolationPoint>

The low end of the scale.

midpoint: Option<InterpolationPoint>

An optional midpoint.

maxpoint: Option<InterpolationPoint>

The high end of the scale.
