However, because Ztunnel operates only at Layer 4, we are in a tricky position:
* TCP is stateful, so we cannot really just pass state over to the other process.
  If we operated at L3 we could just start processing packets in the new Ztunnel.
* We do not operate at L7, so we cannot signal to the application, in any way, that it should reconnect (to the new Ztunnel).

Realistically, that means the best we can do is:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[9] *}

In this case, **FastAPI** won't ever touch or care about `__init__`, we will use it directly in our code.

## Create an instance

We could create an instance of this class with:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}

- **Reduce the size of the Gradle distribution** - We no longer need to carry multiple standard libraries for different languages.

## Decision

We do not introduce new public API methods that include Groovy types in their signatures.
Existing Groovy methods will not be removed immediately.

## Status

ACCEPTED

## Consequences

    "EqualsGetClass", // Let's agree if we want to adopt Error Prone's idea of valid equals()
    "JdkObsolete", // Most of the checks are good, but we do not want to replace all LinkedLists without a good reason

    // NEVER
    "MissingSummary", // We have another mechanism to check Javadocs on public API
    "InjectOnConstructorOfAbstractClass", // We use abstract injection as a pattern

```

But that is still not that useful.

Let's make it give us the current user.

## Create a user model

First, let's create a Pydantic user model.

The same way we use Pydantic to declare bodies, we can use it anywhere else:

//// tab | Python 3.10+

```Python hl_lines="5  12-16"
{!> ../../docs_src/security/tutorial002_an_py310.py!}
```

////

//// tab | Python 3.9+

  chmod +x "/usr/local/bin/bazel"

# "TFCI_MACOS_UPGRADE_PYENV_ENABLE" is used to decide if we need to upgrade the
# Pyenv version. We enable this for macOS x86 builds as the default Pyenv on
# those VMs does not support installing Python 3.12 and above which we need
# for running smoke tests in nightly/release wheel builds.
if [[ "${TFCI_MACOS_UPGRADE_PYENV_ENABLE}" == 1 ]]; then

collaborative, shared environment, and goals. We expect it to be followed in spirit as much as in
the letter.

Diversity Statement
-------------------

We encourage everyone to participate and are committed to building a community for all. Although we
may not be able to satisfy everyone, we all agree that everyone is equal.

Whenever a participant has made a mistake, we expect them to take responsibility for it. If someone

So, if we create a Pydantic object `user_in` like:

```Python
user_in = UserIn(username="john", password="secret", email="******@****.***")
```

and then we call:

```Python
user_dict = user_in.dict()
```

we now have a `dict` with the data in the variable `user_dict` (it's a `dict` instead of a Pydantic model object).

And if we call:

```Python
print(user_dict)
```

        it just seem like a sensible behavior for the feature to have?


        Before we make significant changes to existing features in Guava, we really want to be sure
        that it's for a use case that actually comes up in the real world. We want to hear the
        real-world use case so the community can discuss and debate whether this feature is actually
