Decoding struct to struct

[dennis-dko]

Hello,

I want to decode the values from a struct to another struct, it works for all primitive datatypes but not for custom types like the Foobar example which uses the World struct as new custom type for Hello.

type World struct {
    time.Time
} 

type Foobar struct {
    Hello World 
} 

type Dest struct {
  CurrentTime World `mapstructure:"Hello"`
} 


src := Foobar{
 Hello: time.Now(), 
} 

var dest Dest

mapstructure.Decode(src, &dest) 

I have the same problem with sql.NullString.

The problem is I have to decode the complete struct in the hook function and I hope I can do it easier.
