Struct Scalar

pub struct Scalar { /* private fields */ }

A single logical item, composed of both a ScalarValue and a logical DType.

A ScalarValue is opaque, and should be accessed via one of the type-specific scalar wrappers for example BoolScalar, PrimitiveScalar, etc.

Note that PartialOrd is implemented only for an exact match of the scalar’s dtype, including nullability. When the DType does match, ordering is nulls first (lowest), then the natural ordering of the scalar value.

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

Compares two scalar values for ordering.

Returns

Ordering Rules

When types match, the ordering follows these rules:

• Null values are considered less than all non-null values
• Non-null values are compared according to their natural ordering

Examples

// Same types compare successfully
let a = Scalar::primitive(10i32, Nullability::NonNullable);
let b = Scalar::primitive(20i32, Nullability::NonNullable);
assert_eq!(a.partial_cmp(&b), Some(Ordering::Less));

// Different types return None
let int_scalar = Scalar::primitive(10i32, Nullability::NonNullable);
let str_scalar = Scalar::utf8("hello", Nullability::NonNullable);
assert_eq!(int_scalar.partial_cmp(&str_scalar), None);

// Nulls are less than non-nulls
let null = Scalar::null(DType::Primitive(PType::I32, Nullability::Nullable));
let value = Scalar::primitive(0i32, Nullability::Nullable);
assert_eq!(null.partial_cmp(&value), Some(Ordering::Less));

fn lt(&self, other: &Rhs) -> bool
