Unary operators

Variants

AtDashAt

@-@ Length or circumference (PostgreSQL/Redshift geometric operator) see https://www.postgresql.org/docs/9.5/functions-geometry.html

BangNot

Unary logical not operator: e.g. ! false (Hive-specific)

BitwiseNot

Bitwise Not, e.g. ~9

DoubleAt

@@ Center (PostgreSQL/Redshift geometric operator) see https://www.postgresql.org/docs/9.5/functions-geometry.html

Hash

# Number of points in path or polygon (PostgreSQL/Redshift geometric operator) see https://www.postgresql.org/docs/9.5/functions-geometry.html

Plus

Plus, e.g. +9

Minus

Minus, e.g. -9

Not

Not, e.g. NOT(true)

PGAbs

Absolute value, e.g. @ -9 (PostgreSQL-specific)

PGCubeRoot

Cube root, e.g. ||/27 (PostgreSQL-specific)

PGPostfixFactorial

Factorial, e.g. 9! (PostgreSQL-specific)

PGPrefixFactorial

Factorial, e.g. !!9 (PostgreSQL-specific)

PGSquareRoot

Square root, e.g. |/9 (PostgreSQL-specific)

QuestionDash

?- Is horizontal? (PostgreSQL/Redshift geometric operator) see https://www.postgresql.org/docs/9.5/functions-geometry.html

QuestionPipe

?| Is vertical? (PostgreSQL/Redshift geometric operator) see https://www.postgresql.org/docs/9.5/functions-geometry.html

Trait Implementations

impl Clone for UnaryOperator

fn clone(&self) -> UnaryOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnaryOperator

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

Formats the value using the given formatter.

impl Display for UnaryOperator

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

Formats the value using the given formatter.

impl Hash for UnaryOperator

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

where __H: Hasher,

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 Ord for UnaryOperator

fn cmp(&self, other: &UnaryOperator) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for UnaryOperator

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

fn partial_cmp(&self, other: &UnaryOperator) -> 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 Visit for UnaryOperator

fn visit<V>(&self, visitor: &mut V) -> ControlFlow<<V as Visitor>::Break>

where V: Visitor,

Visit this node with the provided Visitor.

impl VisitMut for UnaryOperator

fn visit<V>(&mut self, visitor: &mut V) -> ControlFlow<<V as VisitorMut>::Break>

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.

impl Copy for UnaryOperator

impl Eq for UnaryOperator

impl StructuralPartialEq for UnaryOperator
