newTag :: Tag Source #

Create a value of Tag with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:value:Tag', tag_value - A user-defined value, which is optional in a tag. For more information, see Tag Clusters.

$sel:key:Tag', tag_key - A user-defined key, which is the minimum required information for a valid tag. For more information, see Tag .

tag_value :: Lens' Tag (Maybe Text) Source #

A user-defined value, which is optional in a tag. For more information, see Tag Clusters.

tag_key :: Lens' Tag (Maybe Text) Source #

A user-defined key, which is the minimum required information for a valid tag. For more information, see Tag .
