Variants

Knobs

Knob preset — WidgetCatalog::build runs and consults knobs() to build the widget; the supplied overrides are applied on top of the spec’s defaults.

Fields

name: &'static str

overrides: KnobOverrides

Scenario

Hand-authored scenario — WidgetCatalog::build ignores its KnobValues argument when this variant is selected and instead dispatches to the captured builder fn.

Fields

name: &'static str

builder: ScenarioBuilder
