## `Union` or `anyOf`

You can declare a response to be the `Union` of two or more types, that means, that the response would be any of them.

It will be defined in OpenAPI with `anyOf`.

   * point values. Two instances are guaranteed to be considered equal if one is copied from the
   * other using {@code second = new StatsAccumulator().addAll(first).snapshot()}, if both were
   * obtained by calling {@code snapshot()} on the same {@link StatsAccumulator} without adding any
   * values in between the two calls, or if one is obtained from the other after round-tripping

  // Graph identity

   * Returns {@code true} iff {@code object} is a {@link Graph} that has the same elements and the
   * same structural relationships as those in this graph.
   *
   * <p>Thus, two graphs A and B are equal if <b>all</b> of the following are true:
   *
   * <ul>
   *   <li>A and B have equal {@link #isDirected() directedness}.
   *   <li>A and B have equal {@link #nodes() node sets}.

would be valid to use as a **FastAPI** dependency.

In fact, FastAPI uses those two decorators internally.

## A database dependency with `yield`

For example, you could use this to create a database session and close it after finishing.

HTTPS
=====

OkHttp attempts to balance two competing concerns:

 * **Connectivity** to as many hosts as possible. That includes advanced hosts that run the latest versions of [boringssl](https://boringssl.googlesource.com/boringssl/) and less out of date hosts running older versions of [OpenSSL](https://www.openssl.org/).
