pub fn parse_cdxml_all(
input: &str,
) -> Result<Vec<(Molecule, Vec<(f64, f64)>)>, CdxmlError>Expand description
Parse all molecular fragments from a CDXML document.
Each <fragment> element in the document is parsed as a separate
molecule. Returns a Vec of (Molecule, 2D-coords) pairs in document
order. Coordinates are in CDXML point units (1/72 inch).
§Stereochemistry
Wedge bonds are derived from the Display attribute of <b> elements:
"WedgeBegin" / "WedgedHashBegin" → BondOrder::Up;
"Hash" / "Dash" / "WedgeEnd" / "WedgedHashEnd" → BondOrder::Down.
