str
Required. The name of the tag template field. Example:
- projects/{project_id}/locations/{location}/tagTemplates/{tag_template_id}/fields/{tag_template_field_id}
tag_template_field
`.gcd_tags.TagTemplateField`
Required. The template to update.
update_mask
`.field_mask.FieldMask`
Optional. The field mask specifies the parts of the template
to be updated. Allowed fields:
- ``display_name``
- ``type.enum_type``
- ``is_required``
If ``update_mask`` is not set or empty, all of the allowed
fields above will be updated.
When updating an enum type, the provided values will be
merged with the existing values. Therefore, enum values can
only be added, existing enum values cannot be deleted nor
renamed. Updating a template field from optional to required
is NOT allowed.
