)
    external
    payable
    returns (address[] memory assets, uint256[] memory assetAmounts)

The function to be called when a user wants to liquidate their position. Support liquidation with hot borrowing or not.

_account

address

The address of the borrower

_prjInfo

struct Asset.Info

Information about the project token, including its address and type.

_lendingInfo

struct Asset.Info
