I'd like to swap the rows/columns of a given 2D ndarray idiomatically. I've found this question: #545, which explains that one can create two mutable array views, however it doesn't explain how this is done. I've done something hacky, like so,
fn swap(mut keys: KeysViewMut, i: usize, j: usize) {
let mut row_x = keys.index_axis_mut(ndarray::Axis(0), 0);
row_x.swap(i, j);
{
let mut row_y = keys.index_axis_mut(ndarray::Axis(0), 1);
row_y.swap(i, j);
}
{
let mut row_z = keys.index_axis_mut(ndarray::Axis(0), 2);
row_z.swap(i, j);
}
{
let mut row_l = keys.index_axis_mut(ndarray::Axis(0), 3);
row_l.swap(i, j);
}
}To ensure that the borrows are in their own scope.
