Expand description

Struct-specific accessors.

Slot accessors (validity, fields, slots_view) live on the generated StructArraySlotsExt supertrait; this trait layers struct-specific lookups on top.

Provided Methods§

Source

fn iter_unmasked_fields(&self) -> impl ExactSizeIterator<Item = &ArrayRef> + '_

Iterate over the field arrays in declaration order.

Source

fn unmasked_field_opt(&self, idx: usize) -> Option<&ArrayRef>

The field array at idx, or None if idx is out of bounds.

Use this over unmasked_field when the index comes from outside the library and an out-of-bounds value is an error to report rather than a bug to panic on.
