Function arrow_ord::cmp::not_distinct

pub fn not_distinct(
    lhs: &dyn Datum,
    rhs: &dyn Datum
) -> Result<BooleanArray, ArrowError>

Perform left IS NOT DISTINCT FROM right operation on two Datum

not_distinct is similar to eq, only differing in null handling. In particular, two operands are considered NOT DISTINCT if they have the same value or if both of them is NULL. The result of not_distinct is never NULL.

For floating values like f32 and f64, this comparison produces an ordering in accordance to the totalOrder predicate as defined in the IEEE 754 (2008 revision) floating point standard. Note that totalOrder treats positive and negative zeros as different. If it is necessary to treat them as equal, please normalize zeros before calling this kernel.

Please refer to f32::total_cmp and f64::total_cmp
