Functions

computeGrowthFactors

Computes and returns the new supply/borrow growth factors associated to the given market's pool & peer-to-peer indexes.

function computeGrowthFactors(
    uint256 _newPoolSupplyIndex,
    uint256 _newPoolBorrowIndex,
    Types.PoolIndexes memory _lastPoolIndexes,
    uint256 _p2pIndexCursor,
