modal.parameter

def parameter(*, default: Any = _no_default, init: bool = True) -> Any:

Used to specify options for modal.cls parameters, similar to dataclass.field for dataclasses

class A:
    a: str = modal.parameter()

If init=False is specified, the field is not considered a parameter for the Modal class and not used in the synthesized constructor. This can be used to optionally annotate the type of a field that’s used internally, for example values being set by @enter lifecycle methods, without breaking type checkers, but it has no runtime effect on the class.
