# normalize and hash it, then wrap it in UserIdentifier objects.
# Create a separate UserIdentifier object for each.
# The data in this example is hardcoded, but in your application
# you might read the raw data from an input file.
#
# IMPORTANT: Since the identifier attribute of UserIdentifier
# (https://developers.google.com/google-ads/api/reference/rpc/latest/UserIdentifier)
# is a oneof
# (https://protobuf.dev/programming-guides/proto3/#oneof-features), you must set
# only ONE of hashed_email, hashed_phone_number, mobile_id, third_party_user_id,
# or address-info. Setting more than one of these attributes on the same UserIdentifier
# will clear all the other members of the oneof. For example, the following code is
# INCORRECT and will result in a UserIdentifier with ONLY a hashed_phone_number:
#
# my $incorrect_user_identifier = Google::Ads::GoogleAds::V19::Common::UserIdentifier->new({
#   hashedEmail => '...',
#   hashedPhoneNumber => '...',
# });
