Thank you Alex for the link. Will check it out. To further clarify, the issue I am having is with:
opts …func(*procStruct) opts …func(*sysStruct) I have multiple structs other than *procStruct (as listed in the example), so I am trying to find the best way to generalize this parameter so I can have a common parameter for my factories. Here is a reference link for the pattern I am using for inspiration: http://matthewbrown.io/2016/01/23/factory-pattern-in-golang/ As you can see in the above link, the factories use a common parameter.. however, I am trying to adapt this for functional options.
