Struct PrimitiveScalar

pub struct PrimitiveScalar<'a> { /* private fields */ }

Implementations

impl<'a> PrimitiveScalar<'a>

pub fn try_new(dtype: &'a DType, value: &ScalarValue) -> VortexResult<Self>

pub fn dtype(&self) -> &'a DType

pub fn ptype(&self) -> PType

pub fn pvalue(&self) -> Option<PValue>

pub fn typed_value<T: NativePType + TryFrom<PValue, Error = VortexError>>( &self, ) -> Option<T>

pub fn as_<T: FromPrimitiveOrF16>(&self) -> VortexResult<Option<T>>

Attempt to extract the primitive value as the given type. Fails on a bad cast.

pub fn checked_sub( self, other: PrimitiveScalar<'a>, ) -> VortexResult<Option<Self>>

impl<'a> PrimitiveScalar<'a>

pub fn checked_binary_numeric( self, other: PrimitiveScalar<'a>, op: BinaryNumericOperator, ) -> VortexResult<Option<PrimitiveScalar<'a>>>

Apply the (checked) operator to self and other using SQL-style null semantics.

If the operation overflows, Ok(None) is returned.

If the types are incompatible (ignoring nullability), an error is returned.

If either value is null, the result is null.

Trait Implementations

impl<'a> Clone for PrimitiveScalar<'a>

fn clone(&self) -> PrimitiveScalar<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for PrimitiveScalar<'a>

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

Formats the value using the given formatter.

impl From<PrimitiveScalar<'_>> for Scalar

fn from(pscalar: PrimitiveScalar<'_>) -> Self

Converts to this type from the input type.

impl<'a> Hash for PrimitiveScalar<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for PrimitiveScalar<'a>

fn eq(&self, other: &PrimitiveScalar<'a>) -> 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 PrimitiveScalar<'_>

Ord is not implemented since it’s undefined for different nullability

fn partial_cmp(&self, other: &Self) -> 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 Sub for PrimitiveScalar<'_>

type Output = Result<PrimitiveScalar<'_>, VortexError>

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl<'a> TryFrom<&'a Scalar> for PrimitiveScalar<'a>

type Error = VortexError

The type returned in the event of a conversion error.

fn try_from(value: &'a Scalar) -> Result<Self, Self::Error>

Performs the conversion.
