Contextual autocomplete for properties of a struct?

I'm just starting out with Go and also Go in Vim, but it seems like I'm able to use a strut with deoplete, but when I enter the declaration, it doesn't seem to suggest the properties that are available.

I'm unsure if this is a missing keybinding, feature, outside of scope, yet to be built, etc

Let me know if you need any further clarification!
