ExtractFeatureMapTypes

type ExtractFeatureMapTypes<TFeatures, TFeatureMap> = IsAny<TFeatures> extends true ? UnionToIntersection<TFeatureMap[keyof TFeatureMap]> : UnionToIntersectionOrEmpty<TFeatureMap[Extract<keyof TFeatures, keyof TFeatureMap>]>;

type ExtractFeatureMapTypes<TFeatures, TFeatureMap> = IsAny<TFeatures> extends true ? UnionToIntersection<TFeatureMap[keyof TFeatureMap]> : UnionToIntersectionOrEmpty<TFeatureMap[Extract<keyof TFeatures, keyof TFeatureMap>]>;

Defined in: types/TableFeatures.ts:43

Extracts the API/types contributed by the features present in TFeatures.

TFeatureMap maps feature keys to the types they contribute. When TFeatures is any, all feature-map entries are included to preserve the permissive behavior expected by broad table types. Otherwise, only entries whose keys are present in TFeatures are intersected together.

Type Parameters

TFeatures

TFeatureMap
