A set of types, type checks, and type guards for simpler, safer, and easier to read code.

/**
 * asserts that an object has an id
 */
export type HasId<T> = T & {
    id: number;
};
/**
 * checks whether not an object that may have an id does have the id, at runtime
 */
export declare const hasId: <T extends {
    id?: undefined | number;
}>(obj: T) => obj is HasId<T>;
