brewinglib-generic 0.0.1rc5

Convert a class with generic type parameters to be generic at runtime.

runtime-generic

Decorator that makes some class's generic be able to be instantiated.

Given a class of type T, decorating with this will allow creation of a subclass with generic parameters mapped to matching unbound class attributes.

Example

from brewinglib.generic import runtime_generic

@runtime_generic
class SomeGenericClass[A, B]:
    attr_a: type[A]
    attr_b: type[B]


class ThingA:
    thinga = "foo"


class ThingB:
    thingb = "bar"


assert SomeGenericClass[ThingA, ThingB]().attr_a.thinga == "foo"
assert SomeGenericClass[ThingA, ThingB]().attr_b.thingb == "bar"
