Trait xso::IntoOptionalXmlText

pub trait IntoOptionalXmlText {
    // Required method
    fn into_optional_xml_text(self) -> Result<Option<String>, Error>;
}

Specialized variant of IntoXmlText.

Do not implement this unless you cannot implement IntoXmlText: implementing IntoXmlText is more versatile and an IntoOptionalXmlText implementation is automatically provided.

If you need to customize the behaviour of the IntoOptionalXmlText blanket implementation, implement a custom IntoXmlText::into_optional_xml_text instead.
