| toUser   | address | The address of the delegatee       |
| asset    | address | The address of the delegated asset |
| amount   | uint256 | The amount being delegated         |

## approveDelegation

```solidity
function approveDelegation(address delegatee, uint256 amount) external
```

Delegates borrowing power to a user on the specific debt token.\
Delegation will still respect the liquidation constraints (even if delegated, a\
delegatee cannot force a delegator HF to go below 1)

### Parameters

| Name      | Type    | Description                                         |

| amount    | uint256 | The maximum amount being delegated.                 |

## borrowAllowance

```solidity
function borrowAllowance(address fromUser, address toUser) external view returns (uint256)
```

Returns the borrow allowance of the user

### Parameters

| Name     | Type    | Description                   |
| -------- | ------- | ----------------------------- |
| fromUser | address | The user to giving allowance  |

### Return Values

| Name | Type    | Description                       |
| ---- | ------- | --------------------------------- |
| \[0] | uint256 | The current allowance of `toUser` |

## delegationWithSig

```solidity
function delegationWithSig(address delegator, address delegatee, uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) external
```

Delegates borrowing power to a user on the specific debt token via ERC712 signature

### Parameters

| deadline  | uint256 | The deadline timestamp, type(uint256).max for max deadline |
| v         | uint8   | The V signature param                                      |
