How to create a "class object" in C++?

I have a model that takes a Python class as a parameter to forward():

class Inputs:
    def __init__(self, a:Tensor, b:Tensor, c:Tensor):
        self.a = a
        self.b = b
        self.c = c

class Model(nn.Module):
    def forward(self, inputs: Inputs):

After converting it to a ScriptedModule and saving to a file, I would like to load and use this model in a C++ program.
However, I am not sure what would be the equivalent of Inputs class on the C++ side… Any pointers to docs/examples that show how to do this?
