## Data members

### dtype\_ {#dtype_}

<div class="api-signature">

`std::optional<`[`DataType`](../../index.md#DataType)`>` **`dtype_`**

</div>

The dtype the gathered rows decode to, one of Float32 / Float16 / BFloat16; unset (the default) selects the scheme's own float target. The packed codes are never cast.

### device\_ {#device_}

<div class="api-signature">

`std::optional<`[`Device`](../Device.md)`>` **`device_`**

</div>

[Where](./Where.md) the table lives; unset (the default) is the weight's own placement for the from-weight `make`, CPU for the declared form.
