pub fn and_not(
left: &BooleanArray,
right: &BooleanArray,
) -> Result<BooleanArray, ArrowError>
Expand description
Performs AND_NOT
operation on two arrays. If either left or right value is null then the
result is also null.
§Error
This function errors when the arrays have different lengths.
§Example
let a = BooleanArray::from(vec![Some(false), Some(true), None]);
let b = BooleanArray::from(vec![Some(true), Some(true), Some(false)]);
let andn_ab = and_not(&a, &b).unwrap();
assert_eq!(andn_ab, BooleanArray::from(vec![Some(false), Some(false), None]));
// It's equal to and(left, not(right))
assert_eq!(andn_ab, and(&a, ¬(&b).unwrap()).unwrap());
