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.

Implementations

impl Scalar

pub fn binary(buffer: impl Into<ByteBuffer>, nullability: Nullability) -> Self

Creates a new binary scalar from a byte buffer.

impl Scalar

pub fn primitive<T: NativePType + Into<PValue>>( value: T, nullability: Nullability, ) -> Self

Creates a new primitive scalar from a native value.

pub fn primitive_value( value: PValue, ptype: PType, nullability: Nullability, ) -> Self

Create a PrimitiveScalar from a PValue.

Note that an explicit PType is passed since any compatible PValue may be used as the value for a primitive type.

pub fn reinterpret_cast(&self, ptype: PType) -> Self

Reinterprets the bytes of this scalar as a different primitive type.

Panics

Panics if the scalar is not a primitive type or if the types have different byte widths.

impl Scalar

pub fn new(dtype: DType, value: ScalarValue) -> Self

Creates a new scalar with the given data type and value.

pub fn dtype(&self) -> &DType

Returns a reference to the scalar’s data type.

pub fn value(&self) -> &ScalarValue

Returns a reference to the scalar’s underlying value.

pub fn into_parts(self) -> (DType, ScalarValue)

Consumes the scalar and returns its data type and value as a tuple.

pub fn into_dtype(self) -> DType

Consumes the scalar and returns its underlying DType.

pub fn into_value(self) -> ScalarValue

Creates a null scalar with the given nullable data type.

Panics

pub fn null_typed<T: NativeDType>() -> Self

The resulting scalar will have a nullable version of the type’s data type.

pub fn cast(&self, target: &DType) -> VortexResult<Self>

pub fn nbytes(&self) -> usize

pub fn zero_value(dtype: DType) -> Self

Creates a “zero”-value scalar value for the given data type.

For nullable types the zero value is the underlying DType’s zero value.

Zero Values

Here is the list of zero values for each DType (when the DType is non-nullable):

• Bool: false
• Primitive: 0
• Decimal: 0
• Utf8: ""
• Binary: An empty buffer
• List: An empty list
• FixedSizeList: A list (with correct size) of zero values, which is determined by the element DType
• Struct: A struct where each field has a zero value, which is determined by the field DType
• Extension: The zero value of the storage DType

This is similar to default_value except in its handling of nullability.

pub fn default_value(dtype: DType) -> Self

• Null: null
• Bool: false
• Primitive: 0
• Decimal: 0
• Utf8: ""
• Binary: An empty buffer
• List: An empty list
• FixedSizeList: A list (with correct size) of default values, which is determined by the element DType
• Struct: A struct where each field has a default value, which is determined by the field DType
• Extension: The default value of the storage DType

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));
