Struct pallet_interest_accrual::pallet::Pallet

impl<T: Config> Pallet<T>

pub fn get_debt( interest_rate_per_year: &InterestRate<T::Rate>, normalized_debt: T::Balance, when: Seconds ) -> Result<T::Balance, DispatchError>

Calculate fastly the current debt using normalized debt * cumulative rate if when is exactly now (same block). If when is in the past it recomputes the previous cumulative rate.

If when is further in the past than the last time the normalized debt was adjusted, this will return nonsense (effectively “rewinding the clock” to before the value was valid)

pub fn do_renormalize_debt( old_interest_rate: &InterestRate<T::Rate>, new_interest_rate: &InterestRate<T::Rate>, normalized_debt: T::Balance ) -> Result<T::Balance, DispatchError>
