Type Alias: AssertScenePlaceableDriver<Ctor>

AssertScenePlaceableDriver<Ctor> = Ctor

Defined in: packages/core/src/partTypes.ts:140

Compile-time lock for the composite-driver authoring rule. Resolves to Ctor when it satisfies ScenePlaceableDriverCtor and errors at the type argument otherwise, so a package turns the rule into a build error in one line:

// MyCompositeDriver must stay scene-placeable
type _Lock = AssertScenePlaceableDriver<typeof MyCompositeDriver>;

Because constructor parameters are checked contravariantly, a driver whose option parameter is typed the "natural" Partial<IComponentDriverOption<typeof parts>> way fails this assertion — exactly the trap the rule guards against (see ComponentDriver). This is the reusable form of the type-test that @atomic-testing/component-driver-html ships as precedent.
