rerun._rerun2._converters

Utility converter functions to make attrs and mypy happy.

As of version 1.4.1, mypy (and possibly other tooling) doesn't properly recognize converters passed to attrs fields. For example, consider this class:

from attrs import define, field
import numpy as np
import numpy.typing as npt

@define
class ClassA:
    xy: npt.NDArray[np.float32]= field(converter=CONVERTER)

mypy is only happy if CONVERTER is a regular, properly-typed function. In particular, it rejects both of these correct and more compact alternatives: - lambda data: np.array(data, dtype=np.float32) - functools.partial(np.array, dtype=np.float32)
