Types
This module contains a set of type aliases for isqx physical quantity kinds
and units.
Usage
When annotating functions, use unconstrained generic types:
from aerocore import types as t
def foo(x: t.StaticTemperatureK) -> t.PressurePA:
...
This signals to the static type checker that we want an Unknown type, not the
Any type. Do not annotate with NDArray[np.float64] or float.
Reasoning: we wish to support a wide range of numerical libraries, so
restricting ourselves to numpy will lead to many false positives in strict
mode. See https://docs.jax.dev/en/latest/jep/12049-type-annotations.html
for more information.
