Golang: Having trouble with nested JSON Unmarshaler

Question

Given the following code:

package main

import (
    \"encoding/json\"
    \"log\"
)

type Somefin string

func (s *Somefin) UnmarshalJSON(b []byte) error {
             


        

Answer 1

I figured this out.

If you have the struct definition like this:

type Wat struct {
    A, B string
    Somefin
}

Then the error I described in the OP happens. But if you do:

type Wat struct {
    A, B string
    Somefin Somefin
}

Then it doesn't. Check out Chris's comment to this answer for a good explanation of why.
