Functions

increaseP2P

Increases the peer-to-peer amounts following a promotion.

function increaseP2P(
    Types.Deltas storage deltas,
    address underlying,
    uint256 promoted,
    uint256 amount,
    Types.Indexes256 memory indexes,
    bool borrowSide
) internal returns (uint256 p2pBalanceIncrease);

Parameters

Name	Type	Description
`deltas`	`Types.Deltas`	The market deltas to update.
`underlying`	`address`	The underlying address.
`promoted`	`uint256`	The amount to increase the promoted side peer-to-peer total (in underlying). Must be lower than or equal to amount.
`amount`	`uint256`	The amount to increase the opposite side peer-to-peer total (in underlying).
`indexes`	`Types.Indexes256`	The current indexes.
`borrowSide`	`bool`	True if this follows borrower promotions. False for supplier promotions.

Returns

Name	Type	Description
`p2pBalanceIncrease`	`uint256`	The scaled balance amount in peer-to-peer to increase.

decreaseP2P

Decreases the peer-to-peer amounts following a demotion.

function decreaseP2P(
    Types.Deltas storage deltas,
    address underlying,
    uint256 demoted,
    uint256 amount,
    Types.Indexes256 memory indexes,
    bool borrowSide
) internal;

Parameters

Name	Type	Description
`deltas`	`Types.Deltas`	The market deltas to update.
`underlying`	`address`	The underlying address.
`demoted`	`uint256`	The amount to decrease the demoted side peer-to-peer total (in underlying). Must be lower than or equal to amount.
`amount`	`uint256`	The amount to decrease the opposite side peer-to-peer total (in underlying).
`indexes`	`Types.Indexes256`	The current indexes.
`borrowSide`	`bool`	True if this follows borrower demotions. False for supplier demotions.
