HLS Best Practices for Parameter Passing

[milleral]

Hello, I am new to using HLS and I am used to the object oriented programming that can be done in C++.

What is the closest analog to making class or a struct so that many parameters can be passed into a component without cluttering the component function's definition?

I have many different components that require similar, but not exactly the same inputs. Would I be losing efficiency if I pass in a single, overarching struct that includes all of these parameters?

Thanks for the input!
