Function toward_xml

pub(crate) fn toward_xml(
    env: Envelope,
    schema: &Schema,
) -> Result<Envelope, String>

Converts env to UCI XML when it is OMS JSON.

Already-XML payloads are labelled and returned. The type hint is replaced with the converted message name. A-GRA EncodedPayload hex is converted the same way as the wrapper.

Errors

Returns a message if the bytes are not UTF-8, the JSON will not parse as a UCI message, or the inner hex cannot be transcoded.
