array – Array-like data (anything ak.to_layout recognizes).

Extracts record fields or tuple slot numbers from array (many types supported, including all Awkward Arrays and Records).

If the array contains nested records, only the outermost record is queried. If it contains tuples instead of records, this function outputs string representations of integers, such as "0", "1", "2", etc. The records or tuples may be within multiple layers of nested lists.

If the array contains neither tuples nor records, this returns an empty list.
