相当于`jq --stream -c`的Golang

Using jq --stream -c on the command line, I can format pretty JSON like this:

{
  "object": {
    "something": {
      "key1": 123,
      "key2": 456
    },
    "something_else": {
      "key1": [
        "value1",
        "value2"
      ]
    }
  }
}

into this:

[["object","something","key1"],123]
[["object","something","key2"],456]
[["object","something","key2"]]
[["object","something_else","key1",0],"value1"]
[["object","something_else","key1",1],"value2"]
[["object","something_else","key1",1]]
[["object","something_else","key1"]]
[["object","something_else"]]
[["object"]]

I've looked through the Golang documentation for JSON but couldn't find anything similar. Is there such a function that I've missed?

More precisely I'd like to print the above JSON like so:

object.something.key1=123
object.something.key2=345
object.something_else.key1.0=value1
object.something_else.key1.1=value2

No, you haven't missed anything. The current JSON library doesn't support what you described "out of the box".

If you want this to work, you'll need to find a package that offers the flexibility you need or satisfy json.Marshaler with a custom type yourself.
