Nested structures

[MilosSimic]

I'm curious how to store and restore nested structures, for example slice/array of structs, or map where key is string and value is some other struct (arbitrarily nested). What would be the best strategy for this?

I was able to store and restore JSON as is, but what If I have some already mapped structs, is it possible to reuse them somehow?
For example:

type TB struct {
B string
DataTB map[string]string
}

type A struct {
A string
DataTA map[string]string
B TB
DataTC map[string]TC
}

At the moment, all thins except DataTC which is map[string]TC, will be stored and restored properly. Only DataTC will end up as an empty map. What is the best solution for this?
