Function find_validity_mismatch

pub fn find_validity_mismatch(
    left: &dyn Array,
    right: &dyn Array,
    idxs: &mut Vec<IdxSize>,
)

Find the indices of the values where the validity mismatches.

This is done recursively, meaning that a validity mismatch at a deeper level will result as at the level above at the corresponding index.

This procedure requires that

• Nulls are propagated recursively
• Lists to be
  • trimmed to normalized offsets
  • have the same number of child elements below each element (even nulls)
