Hardsigmoid(inplace=False)

    Piecewise-linear sigmoid approximation: clamp(input / 6 + 1 / 2, 0, 1).

    The module form of ``clika_runtime.nn.functional.hardsigmoid``: construct
    it once with the settings, then call it like a function.

    Args:
        inplace: whether the forward writes the result into its input and
            returns that input.
    

## `__init__`

```python
__init__(self, inplace: 'bool' = False) -> 'None'
```

Initialize self.  See help(type(self)) for accurate signature.

## `extra_repr`

```python
extra_repr(self) -> 'str'
```

extra_repr() -> str

One line of per-class detail for :meth:`__repr__`; a layer prints
its geometry here (``in_features=64, out_features=256``).

## `forward`

```python
forward(self, input: 'Tensor') -> 'Tensor'
```

forward(input) -> Tensor

Runs ``clika_runtime.nn.functional.hardsigmoid`` on ``input``; returns
a new tensor, or ``input`` itself, holding the result, when ``inplace``
is set.
