如何定义go结构来存储此Yaml结构？

I'm trying to figure out how to organize my Golang structs to store my yaml file. I think I'm having a bit of a problem with the nested maps. I'm trying to get this yaml file to be stored in something like {statCategory:{CatOne:{featD:{description:amazing, unit:nil}}}.

I'm currently using yaml "gopkg.in/yaml.v2" for parsing yaml.

Below is the yaml file that I'm trying to parse.

stat:
  statCategory:
    CatOne:
      featD:
        description: amazing
        unit: nil
      featH:
        description: not amazing
        unit: nil
    CatTwo:
      featA:
        description: hello
        unit: ms
      featB:
        description: something
        unit: ms
      featC:
        description: another description
        unit: ms

I've tried to use the struct below, but it's seem to only kinda work.

type yamlStatDAO struct {
    Stat statCategory `yaml:"stat"`
}
type statCategory struct {
    StatCat map[string]map[string]statInfo `yaml:"statCategory"`
}

type statInfo struct {
    description string `yaml:"description"`
    unit        string `yaml:"unit"`
}

But I only end up with {statCategory:{CatOne:{featD:{}}}. If I can't figure this out, I might just restructure my yaml file.

EDIT: seems like the solution was just to capitalize description and unit.

type statInfo struct {
    Description string `yaml:"description"`
    Unit        string `yaml:"unit"`
}
