withOptions
FunctionwithOptions<K, T>(defaultOptions: IRequestOptions, func: T): (funcArgs: Parameters<T>) => ReturnType<T>Allows you to wrap individual methods with a default set of request options. This is useful to avoid setting the same option more then once and allows for interacting and setting defaults in a functional manner.
