Enum ScalarValue

pub enum ScalarValue {
    Bool(bool),
    Primitive(PValue),
    Buffer(Buffer),
    BufferString(BufferString),
    List(Arc<[ScalarValue]>),
    Null,
}

Represents the internal data of a scalar value. Must be interpreted by wrapping up with a DType to make a Scalar.

Note that these values can be deserialized from JSON or other formats. So a PValue may not have the correct width for what the DType expects. This means primitive values must be cast on-read.

Variants

Bool(bool)

Primitive(PValue)

Buffer(Buffer)

BufferString(BufferString)

List(Arc<[ScalarValue]>)

Null

Implementations

Trait Implementations

impl Clone for ScalarValue

fn clone(&self) -> ScalarValue

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScalarValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ScalarValue

fn eq(&self, other: &ScalarValue) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ScalarValue

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

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
