Function invoice 

pub fn invoice<C: InflationCurve<f64> + ?Sized>(
    bond: &InflationLinkedBond,
    convention: LinkerConvention,
    real_clean: f64,
    settlement: NaiveDate,
    fixings: &FixingsView<'_, f64>,
    curve: &C,
) -> Result<LinkerInvoice, LinkerQuoteError>

The settlement invoice for a real-yield-quoting linker at a real clean quote.

Eight-month-lag gilts are refused rather than served: they quote in money terms already, so scaling a “real clean” by a ratio would index a number that is not real. Their invoice is uk_money_price with uk_money_accrued.

Errors

LinkerQuoteError::WrongFamily outside the real-yield family, including for the eight-month UK generation; curve errors otherwise.
