In-place [`index_copy`](./index_copy.md#index_copy): `self[.., indices[i], ..] = src[.., i, ..]`; same arguments and error conditions as [`index_copy()`](./index_copy.md#index_copy). Writes through `self`'s storage (a strided view, e.g. a cache slice, reaches its base buffer; aliases observe the write). Returns `self` under the value surface, [`Result`](../Result.md)`<void>` under the [`Result`](../Result.md) surface; [`CLIKART_CHECK`](../../index.md#CLIKART_CHECK) is the mode-stable spelling.
