I think, for view arrays, the offsets

Sorry for being misleading. "valid" offset means that:
1. For Binary Like [1] format, and List formats [2], even if the parent
has `validity = false`. Their offset should be well-defined.
Yes.
2. For StringView and ArrayView, if the parent

Thanks all!
So, in general:
1. For our Binary Like [1] format, and List formats [2], if the parent is
not valid, the offset should still be valid
What do you call a "valid" offset?
Thanks all!

2. For the StringView ListView [3] types arrow is currently working on,
if the parent is not valid, the child might has valid content

Values in the `offsets` Buffer of a ListArray can’t be left undefined
because the length of a valid entry before a NULL entry is the offset
associated with that NULL entry minus the previous offset.
The ListViewArray format I’m working on doesn’t have that restriction
because all the information

When a binary array or a list array element is null the cleanest thing to
do is to set the offsets to be the same. So, for example, given a list
array with 5 elements, if second item is null, the offsets could be 0, 8,
8, 12, 20, 50.
Question
I agree with Antoine but I get easily confused by "valid, as in
structurally correct" and "valid, as in not null" so I want to make sure I
understand:

A child must be "structurally correct"

Hi,
By looking at the arrow standard, when it comes to nested structure, like
StructArray[1] or FixedListArray[2], when parent is not valid, the
correspond child leaves "undefined".
If it's a BinaryArray, when when it parent is not valid,
