Function and_then_selectors_with_mask 

Source 
pub(super) fn and_then_selectors_with_mask(
    first: &[RowSelector],
    second: &BooleanBuffer,
) -> RowSelection
Expand description

Applies the mask second to the rows selected by the selector-backed first.

The mask is streamed as RowSelector runs, so it is never materialized.
