   4 AuthResult is the result from the request that was used to obtain a provider
   5 client's Keystone token. It is returned from ProviderClient.GetAuthResult().
   6
   7 The following types satisfy this interface:
   8
   9         github.com/gophercloud/gophercloud/openstack/identity/v2/tokens.CreateResult
  10         github.com/gophercloud/gophercloud/openstack/identity/v3/tokens.CreateResult
  11
  12 Usage example:
  13
  14         import (
  15                 "github.com/gophercloud/gophercloud"
  16                 tokens2 "github.com/gophercloud/gophercloud/openstack/identity/v2/tokens"
  17                 tokens3 "github.com/gophercloud/gophercloud/openstack/identity/v3/tokens"
  18         )
  19
  20         func GetAuthenticatedUserID(providerClient *gophercloud.ProviderClient) (string, error) {
  21                 r := providerClient.GetAuthResult()
  22                 if r == nil {
  23                         //ProviderClient did not use openstack.Authenticate(), e.g. because token
  24                         //was set manually with ProviderClient.SetToken()
  25                         return "", errors.New("no AuthResult available")
  26                 }
  27                 switch r := r.(type) {
  28                 case tokens2.CreateResult:
  29                         u, err := r.ExtractUser()
  30                         if err != nil {
  31                                 return "", err
  32                         }
  33                         return u.ID, nil
  34                 case tokens3.CreateResult:
  35                         u, err := r.ExtractUser()
  36                         if err != nil {
  37                                 return "", err
  38                         }
  39                         return u.ID, nil
  40                 default:
  41                         panic(fmt.Sprintf("got unexpected AuthResult type %t", r))
  42                 }
  43         }
  44
  45 Both implementing types share a lot of methods by name, like ExtractUser() in
  46 this example. But those methods cannot be part of the AuthResult interface
  47 because the return types are different (in this case, type tokens2.User vs.
  48 type tokens3.User).
