Marshal Embedded Struct

Question

I was playing around to learn how embedding works. http://play.golang.org/p/oHOim4G1-l

When I marshalled Child struct it marshals as {} . Why does it marshal like this?

Your JSON dictionary is empty because none of the fields of the struct (or any of the structures embedded inside the struct) are exported .

If you change the field names to start with an upper case letter, then the encoding/json module will be able to see them. Of course since you've also got methods called Name and Value , you'll need to call them something else to avoid a conflict.
