Struct vortex_scalar::ScalarValue

pub struct ScalarValue(/* private fields */);

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. Primitive values should therefore be read using crate::PrimitiveScalar which will handle the conversion.

Implementations

impl ScalarValue

pub fn is_instance_of(&self, dtype: &DType) -> bool

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<'de> Deserialize<'de> for ScalarValue

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ScalarValue

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

Formats the value using the given formatter.

impl From<&ScalarValue> for ScalarValue

fn from(value: &ScalarValue) -> Self

Converts to this type from the input type.

impl From<bool> for ScalarValue

fn from(value: bool) -> Self

Converts to this type from the input type.

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.

impl Serialize for ScalarValue

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<ScalarValue<'_>> for ScalarValue

type Error = VortexError

The type returned in the event of a conversion error.

fn try_from(value: ScalarValue<'_>) -> Result<Self, Self::Error>

Performs the conversion.

impl WriteFlatBuffer for ScalarValue

type Target<'a> = ScalarValue<'a>

fn write_flatbuffer<'fb>( &self, fbb: &mut FlatBufferBuilder<'fb>, ) -> WIPOffset<Self::Target<'fb>>

impl StructuralPartialEq for ScalarValue
