Enum Operator 

pub enum Operator {
    Eq,
    NotEq,
    Gt,
    Gte,
    Lt,
    Lte,
    And,
    Or,
    Add,
    Sub,
    Mul,
    Div,
}

Equalities, inequalities, and boolean operations over possibly null values.

For most operations, if either side is null, the result is null.

The Boolean operators (And, Or) obey Kleene (three-valued) logic.

Variants

Eq

Expressions are equal.

NotEq

Expressions are not equal.

Gt

Expression is greater than another

Gte

Expression is greater or equal to another

Lt

Expression is less than another

Lte

Expression is less or equal to another

And

Boolean AND (∧).

Or

Boolean OR (∨).

Add

The sum of the arguments.

Errs at runtime if the sum would overflow or underflow.

Sub

The difference between the arguments.

Errs at runtime if the sum would overflow or underflow.

The result is null at any index that either input is null.

Mul

Multiple two numbers

Div

Divide the left side by the right side

Implementations

impl Operator

pub fn inverse(self) -> Option<Self>

pub fn logical_inverse(self) -> Option<Self>

pub fn swap(self) -> Option<Self>

Change the sides of the operator, so that changing lhs and rhs won’t change the result of the operation

pub fn maybe_cmp_operator(self) -> Option<Operator>

pub fn is_arithmetic(&self) -> bool

Trait Implementations

impl Clone for Operator

fn clone(&self) -> Operator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Operator

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Operator

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

Formats the value using the given formatter.

impl From<BinaryOp> for Operator

fn from(value: BinaryOp) -> Self

Converts to this type from the input type.

impl From<Operator> for BinaryOp

fn from(value: Operator) -> Self

Converts to this type from the input type.

impl From<Operator> for Operator

fn from(cmp_operator: Operator) -> Self

Converts to this type from the input type.

impl From<Operator> for i32

fn from(value: Operator) -> Self

impl Hash for Operator

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 PartialEq for Operator

fn eq(&self, other: &Operator) -> 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 Operator

fn partial_cmp(&self, other: &Operator) -> 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 Operator

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<i32> for Operator

type Error = VortexError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.

impl TryInto<Operator> for Operator

type Error = VortexError

The type returned in the event of a conversion error.

fn try_into(self) -> VortexResult<Operator>

Performs the conversion.
