Author: Morpho Labs

Library used to ease increase or decrease deltas.

Functions

increaseDelta

Given variables from a market side, updates the market side delta according to the demoted amount.

function increaseDelta(
    Types.MarketSideDelta storage delta,
    address underlying,
    uint256 amount,
    Types.MarketSideIndexes256 memory indexes,
    bool borrowSide
) internal;

Parameters

Name	Type	Description
`delta`	`Types.MarketSideDelta`	The market deltas to update.
`underlying`	`address`	The underlying address.
`amount`	`uint256`	The amount to supply/borrow (in underlying).
`indexes`	`Types.MarketSideIndexes256`	The current indexes.
`borrowSide`	`bool`	Whether the market side is borrow.

decreaseDelta

Given variables from a market side, matches the delta and calculates the amount to supply/borrow from delta. Updates the market side delta accordingly.

function decreaseDelta(
    Types.MarketSideDelta storage delta,
    address underlying,
    uint256 amount,
    uint256 poolIndex,
    bool borrowSide
) internal returns (uint256, uint256);

Parameters

Name	Type	Description
`delta`	`Types.MarketSideDelta`	The market deltas to update.
`underlying`	`address`	The underlying address.
`amount`	`uint256`	The amount to supply/borrow (in underlying).
`poolIndex`	`uint256`	The current pool index.
`borrowSide`	`bool`	Whether the market side is borrow.

Returns

Name	Type	Description
`<none>`	`uint256`	The amount left to process (in underlying) and the amount to repay/withdraw (in underlying).
`<none>`	`uint256`
