     * Returns permissions that a caller has on the specified resource. If the
     * resource does not exist, this will return an empty set of
     * permissions, not a NOT_FOUND error.
     *
     * Note: This operation is designed to be used for building
     * permission-aware UIs and command-line tools, not for authorization
     * checking. This operation may "fail open" without warning.
     *
     * @param {Object} request
     *   The request object that will be sent.
     * @param {string} request.resource
     *   REQUIRED: The resource for which the policy detail is being requested.
     *   See the operation documentation for the appropriate value for this field.
     * @param {string[]} request.permissions
     *   The set of permissions to check for the `resource`. Permissions with
     *   wildcards (such as '*' or 'storage.*') are not allowed. For more
     *   information see
     *   [IAM Overview](https://cloud.google.com/iam/docs/overview#permissions).
     * @param {Object} [options]
     *   Optional parameters. You can override the default settings for this call, e.g, timeout,
     *   retries, paginations, etc. See [gax.CallOptions]{@link https://googleapis.github.io/gax-nodejs/interfaces/CallOptions.html} for the details.
     * @param {function(?Error, ?Object)} [callback]
     *   The function which will be called with the result of the API call.
     *
     *   The second parameter to the callback is an object representing [TestIamPermissionsResponse]{@link google.iam.v1.TestIamPermissionsResponse}.
     * @returns {Promise} - The promise which resolves to an array.
     *   The first element of the array is an object representing [TestIamPermissionsResponse]{@link google.iam.v1.TestIamPermissionsResponse}.
     *   The promise has a method named "cancel" which cancels the ongoing API call.
