Function arrow2::compute::nullif::primitive_nullif

pub fn primitive_nullif<T>(
    lhs: &PrimitiveArray<T>,
    rhs: &PrimitiveArray<T>
) -> PrimitiveArray<T> where
    T: NativeType + Simd8,
    T::Simd: Simd8PartialEq, 

Available on crate feature compute_nullif only.

Returns an array whose validity is null iff lhs == rhs or lhs is null. This has the same semantics as postgres - the validity of the rhs is ignored.

Panic

This function panics iff

• The arguments do not have the same logical type
• The arguments do not have the same length

Example

let lhs = Int32Array::from(&[None, None, Some(1), Some(1), Some(1)]);
let rhs = Int32Array::from(&[None, Some(1), None, Some(1), Some(0)]);
let result = primitive_nullif(&lhs, &rhs);

let expected = Int32Array::from(&[None, None, Some(1), None, Some(1)]);

assert_eq!(expected, result);
