Run blocking sync code inside of async with `asyncify()`:

```python
from asyncer import asyncify
from fastapi import FastAPI

app = FastAPI()


def do_blocking_work(name: str) -> str:
    # Some blocking I/O operation
    return f"Hello {name}"


@app.get("/items/")
async def read_items():
    result = await asyncify(do_blocking_work)(name="World")
    return {"message": result}
```

        Smb2LeaseKey key = new Smb2LeaseKey(testBytes);
        String str = key.toString();

        assertTrue(str.startsWith("LeaseKey["));
        assertTrue(str.endsWith("]"));
        assertTrue(str.contains("00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F"));
    }

Наприклад, ви можете оголосити, що щось може бути `str` або `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

У `typing` також є скорочення, щоб оголосити, що щось може бути `None`, - `Optional`.
