What do you call this type of class declaration?

I was looking at the Faust docs and I came across syntax for defining class templates (value objects?) in Python that I'd never seen before, and I cannot find any reference to them anywhere I look.

The syntax is:

class Order(faust.Record):
    account_id: str
    amount: int

I really enjoy its simplicity and declarative typing, but I cannot find any documentation on it. Can you help?

These are type annotations / type hints – Robin Gertenbach Sep 23 '21 at 17:31
this seems kinda similar to dataclasses, which are also great – rv.kvetch Sep 23 '21 at 17:33

The built-in [`dataclasses`](https://docs.python.org/3/library/dataclasses.html) work similarly. – interjay Sep 23 '21 at 17:33
