I want to encode pointers differently than from values. Currently, if we have a struct:
type Order struct {
Item Tool
AssociatedItem *Tool
}
both get inlined into a Order document inside mongo when marshalling. I need to be able to perform my own serialization in the case of a *Tool. For instance, I could in this case only store the Id for the Too instead of the whole content. Unfortunately the overriding mechanism in mgo is to define a SetBSON() GetBSON for the Tool but it doesn't differentiate between pointers and non pointers.
What would be the best way to handle this?
