`Header` - это "родственный" класс `Path`, `Query` и `Cookie`. Он также наследуется от того же общего класса `Param`.

That status code will be used in the response and will be added to the OpenAPI schema.

You could also use `from starlette import status`.

**FastAPI** provides the same `starlette.status` as `fastapi.status` just as a convenience for you, the developer. But it comes directly from Starlette.

`Header` ist eine Schwesterklasse von `Path`, `Query` und `Cookie`. Sie erbt von derselben gemeinsamen `Param`-Elternklasse.

Arenas allocate large chunks of memory for Go values, so they're likely to
be inefficient for allocating only small amounts of small Go values. They're
best used in bulk, on the order of MiB of memory allocated on each use.

Note that by allowing for this limited form of manual memory allocation
that use-after-free bugs are possible with regular Go values. This package
limits the impact of these use-after-free bugs by preventing reuse of freed
