        uint256 assetsIn
    )
        external;
```

#### Parameters:

| Index |    Name    |    Type   | Internal Type | Description                |
| :---: | :--------: | :-------: | :-----------: | -------------------------- |
|   0   | `assetsIn` | `uint256` |   `uint256`   | Amount of assets to deploy |

### `requestWithdrawFromStrategy`

Requests withdrawal of assets back to the Maple pool.

```solidity
    function requestWithdrawFromStrategy(
        uint256 assetsOut
    )
        external;
```

#### Parameters:

| Index |     Name    |    Type   | Internal Type | Description                          |
| :---: | :---------: | :-------: | :-----------: | ------------------------------------ |
|   0   | `assetsOut` | `uint256` |   `uint256`   | Amount of assets requested to redeem |

### `removeShares`

Cancels or reduces a pending withdrawal by removing shares.

```solidity
    function removeShares(
        uint256 shares
    )
        external;
```

#### Parameters:

| Index |   Name   |    Type   | Internal Type | Description                               |
| :---: | :------: | :-------: | :-----------: | ----------------------------------------- |
|   0   | `shares` | `uint256` |   `uint256`   | Amount of shares to remove from the queue |

### `removeSharesById`

Cancels or reduces a pending withdrawal by id.

```solidity
    function removeSharesById(
        uint256 requestId,
        uint256 shares
    )
        external;
```

#### Parameters:

| Index |     Name    |    Type   | Internal Type | Description                                  |
| :---: | :---------: | :-------: | :-----------: | -------------------------------------------- |
|   0   | `requestId` | `uint256` |   `uint256`   | Identifier of the withdrawal request         |
|   1   |   `shares`  | `uint256` |   `uint256`   | Amount of shares to remove from that request |

### `pushAssetsToPool`

Pushes any held funds asset back to the pool.

```solidity
    function pushAssetsToPool()
        external;
```

### `reactivateStrategy`

Reactivates a previously impaired or deactivated strategy.

```solidity
    function reactivateStrategy()
        external;
```

### `mapleWithdrawalManager`

Returns the strategy’s configured withdrawal manager.

```solidity
    function mapleWithdrawalManager()
        view
        returns (

event AssetsTransferredToPool(
    address indexed fundAsset,
    address indexed pool,
    uint256 amount
);
```

### `StrategyWithdrawalRequested`
