#### `rebalance(uint256 vaultId,` IMIMORebalance.RebalanceData calldata rbData,`IMIMOSwap.SwapData calldata swapData)`

Performs a rebalance on a vault by an appointed whitelisted manager on behalf of the vault owner.

Requirements :&#x20;

* Contract must be unpaused
* Vault must have been created through the user's `MIMOProxy`
* Vault must be under management
* Caller must be the appointed manager
* Rebalance amount cannot be set to zero
* Maximum daily operation must have not been reached
* Set mint amount cannot be greater than vault debt
* The change in vault value due to the rebalance operation must be lower or equal then the `allowedVariation` set by the owner
* The final vault ratio must be greater or equal then the `minRatio` set by the owner

#### `executeOperation(address[] calldata assets, uint256[] calldata amounts, uint256[] calldata premiums, address initiator, bytes calldata params`

AAVE `Pool` contract flash loan callback function.

Requirements :&#x20;
