Thanks for your reply.

I made an example of what Im trying to do. One thing I didnt specify is the function used is a receiver function. For some reason this means the type had to be instantiated on the receiver itself Spotter in this case. https://goplay.tools/snippet/Vj7uVMi0mWn Basically have two different types that implement an interface, pass them into a receiver function in a composite type (array,slice). Part of the issue is that you cant have the receiver function without defining instantiating the type on the receiver Spotter in this case.

If I'm, again, understanding what's happening, as the example above doesn't compile in its current state, then you'll probably run into this limitation:

I believe the most simple fix would be to have a separate function which is generic that takes in the struct along with the slice of T with the constraints that apply to it.
