Passing the `root_path` to `FastAPI` would be the equivalent of passing the `--root-path` command line option to Uvicorn or Hypercorn.

### About `root_path` { #about-root-path }

Keep in mind that the server (Uvicorn) won't use that `root_path` for anything else than passing it to the app.

Every month, a GitHub Action updates the FastAPI People data. Those PRs look like this one: <a href="https://github.com/fastapi/fastapi/pull/11669" class="external-link" target="_blank">👥 Update FastAPI People</a>.

If the tests are passing, you can merge it right away.

But if you are certain that the content that you are returning is **serializable with JSON**, you can pass it directly to the response class and avoid the extra overhead that FastAPI would have by passing your return content through the `jsonable_encoder` before passing it to the response class.

current implementation may sometimes cause a runtime error if the
contents of the C memory appear to be a Go pointer. Therefore, avoid
passing uninitialized C memory to Go code if the Go code is going to
store pointer values in it. Zero out the memory in C before passing it
to Go.

# Optimizing calls of C code

When passing a Go pointer to a C function the compiler normally ensures
that the Go object lives on the heap. If the C function does not keep

### Existing object replication

Existing object replication as detailed [here](https://aws.amazon.com/blogs/storage/replicating-existing-objects-between-s3-buckets/) can be enabled by passing `existing-objects` as a value to `--replicate` flag while adding or editing a replication rule.

#### Running doctest for testable docstring

There are two ways to test the code in the docstring locally:

1.  If you are only changing the docstring of a class/function/method, then you
    can test it by passing that file's path to
    [tf_doctest.py](https://www.tensorflow.org/code/tensorflow/tools/docs/tf_doctest.py).
    For example:

    ```bash
    python tf_doctest.py --file=<file_path>
    ```

    assertEquals("null [5, 6]", Strings.lenientFormat(null, 5, 6));
    assertEquals("null", Strings.lenientFormat("%s", (Object) null));
  }

    assertEquals("(Object[])null", Strings.lenientFormat("%s", (Object[]) null));
  }
