pub fn write_pdbml(document: &Document) -> Result<String, PdbmlError>Expand description
Writes one lossless document as PDBML/XML.
Both CIF missing sentinels map to XML Schema nil, because PDBML has one
missing representation rather than CIF’s two distinct sentinels.
§Errors
Returns an error when the document has other than one datablock or XML generation fails.
