Trait xso::AsOptionalXmlText

pub trait AsOptionalXmlText {
    // Required method
    fn as_optional_xml_text(&self) -> Result<Option<Cow<'_, str>>, Error>;
}

Specialized variant of AsXmlText.

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

If you need to customize the behaviour of the AsOptionalXmlText blanket implementation, implement a custom AsXmlText::as_optional_xml_text instead.

Required Methods
