Should say that it panics if axis is out of bounds

Thanks. Tests look good enough, it's the same iterator struct. I think we can reuse Can we rename this? |
|
Sure subviews is a nice name. I'll change that when I'm back on my computer. |

So I renamed to |
| // ... | ||
| let mut a = a.to_owned(); | ||
|
|
||
| for mut subview in a.axis_iter_mut(1) { |

mut subview; it's sad quirks like this because we have no user-defined DSTs (views should be unsized like slices I think).

Thank you! I'll fixup the panic info; I don't like using headings in module docs (it doesn't work in many ways). |
Add an iter_axis function to get subviews along an axis
This enables for instance iterating along the columns of a matrix.
Right now the test coverage is basic, so I'll probably add more tests before it is mergeable.
