Function doesn't recognize Yaml nested struct

I have the following struct YAML: 

type YamlConfig struct {
    Items struct {
        RiskyRoles []struct {
            Name string `yaml:"name"`
            Rules []struct{
                Verbs []string `yaml:"verbs"`
                ResourceOperator string `yaml:"resourcesOperator"`
                Resources []string `yaml:"resources"`
            }
        } `yaml:"RiskyRoles"`
    } `yaml:"Items"`
}

I have a function that parse a YAML file to an object and then I want to send the Rules struct object to a function named DoingStuff(..): 

yamlFile, err := ioutil.ReadFile("actionItems.yaml")
if err != nil {
    fmt.Printf("Error reading YAML file: %s\n", err)
} else{
    var yamlConfig YamlConfig
    err = yaml.Unmarshal(yamlFile, &yamlConfig)
    if err != nil {
        fmt.Printf("Error parsing YAML file: %s\n", err)
    }

    for _, yamlRole := range yamlConfig.Items.RiskyRoles{
       DoingStuff(yamlRole.Rules)
    }
}

But inside the function DoingStuff, the struct object Rules is not recognized: 

func DoingStuff(yamlRules []struct{}) {
  // Not recognize ****
  for _, rule := range yamlRules {
      fmt.Print(rule.ResourceOperator)
  }
}

How can I convert it to: 

Rules []struct{
    Verbs []string `yaml:"verbs"`
    ResourceOperator string `yaml:"resourcesOperator"`
    Resources []string `yaml:"resources"`
}

Should I re-declare this struct again? Or cast using interfaces ?

EDIT:

I added new struct and used it inside the YamlConfig struct but the parse failed to parse the Rules: 

type RulesStruct struct {
    Rules []struct{
        Verbs []string `yaml:"verbs"`
        ResourceOperator string `yaml:"resourcesOperator"`
        Resources []string `yaml:"resources"`
    }
}
type YamlConfig struct {
    Items struct {
        RiskyRoles []struct {
            Name string `yaml:"name"`
            Message string `yaml:"message"`
            Priority string `yaml:"priority"`
            Rules []RulesStruct
        } `yaml:"RiskyRoles"`
    } `yaml:"Items"`
}

Thanks to @mkporiva help, I changed the structs like that: 

type RulesStruct struct {

    Verbs []string `yaml:"verbs"`
    ResourceOperator string `yaml:"resourcesOperator"`
    Resources []string `yaml:"resources"`

}

type YamlConfig struct {
    Items struct {
        RiskyRoles []struct {
            Name string `yaml:"name"`
            Message string `yaml:"message"`
            Priority string `yaml:"priority"`
            Rules []RulesStruct
        } `yaml:"RiskyRoles"`
    } `yaml:"Items"`
}

Now it works fine.
