Required methods

fn save_uncredited_settlement_amount(
    &self,
    account_id: Self::AccountId,
    uncredited_settlement_amount: (Self::AssetType, u8)
) -> Box<dyn Future<Item = (), Error = ()> + 'static + Send>

Saves the leftover data

fn load_uncredited_settlement_amount(
    &self,
    account_id: Self::AccountId,
    local_scale: u8
) -> Box<dyn Future<Item = Self::AssetType, Error = ()> + 'static + Send>

Returns the leftover data scaled to local_scale from the saved scale. If any precision loss occurs during the scaling, it should be saved as the new leftover value.
