Type Alias CompleteRequire<Parent>

CompleteRequire: {
    [Prop in keyof Parent]-?: Parent extends Partial<Record<Prop, infer V>>
        ? V
        : never
}

Requires every part of an object, even the indexed keys. This is needed because Required<Partial<T>> doesn't fully remove | undefined from indexed keys when the noUncheckedIndexedAccess TSConfig compiler option is enabled.
