_getUpdateDebtReserves

function _getUpdateDebtReserves(uint256 shares_, uint256 totalShares_, struct Structs.DebtReserves d_, bool mintOrBurn_) internal pure returns (struct Structs.DebtReserves d2_)

Updates debt and reserves based on minting or burning shares

_This function calculates the new debt and reserves when minting or burning shares. It updates the following for both tokens:

• Debt
• Real Reserves
• Imaginary Reserves The calculation is done proportionally based on the ratio of shares to total shares. For minting, it adds the proportional amount. For burning, it subtracts the proportional amount._

Name	Type	Description
shares_	uint256	The number of shares to mint or burn
totalShares_	uint256	The total number of shares before the operation
d_	struct Structs.DebtReserves	The current debt and reserves
mintOrBurn_	bool	True if minting, false if burning

Return Values

Name	Type	Description
d2_	struct Structs.DebtReserves	The updated debt and reserves
