     * @param options The optional options used to configure this method.
     * @param options.startTime This parameter does nothing.
     * @param options.maxTime The time in milliseconds this method may take before throwing an error. Defaults to `50`.
     * @param options.maxRetries The total number of attempts to try before throwing an error. Defaults to `50`.
     * @param options.currentIterations This parameter does nothing.
     * @param options.exclude The value or values that should be excluded/skipped. Defaults to `[]`.
     * @param options.compare The function used to determine whether a value was already returned. Defaults to check the existence of the key.
     * @param options.store The store of unique entries. Defaults to a global store.

     * @example
     * faker.unique(faker.name.firstName) // 'Corbin'
