Function quantmath::facade::market_data_from_json

pub fn market_data_from_json(source: &mut Read) -> Result<RcMarketData, Error>

MarketData contains all the live market data required for pricing. This is spots, yield and borrow curves, dividends, volatilities, and correlations. You can instantiate a MarketData as here by deserializing it from json. It may be more efficient to instantiate it directly, by using methods in the data module.
