An enum that represents operators in the operator tree.

Variants

RootNode

A root node in the operator tree. The whole expression is stored under a root node, as well as each subexpression surrounded by parentheses.

Add

A binary addition operator.

Sub

A binary subtraction operator.

Neg

A unary negation operator.

Mul

A binary multiplication operator.

Div

A binary division operator.

Mod

A binary modulo operator.

Exp

A binary exponentiation operator.

Eq

A binary equality comparator.

Neq

A binary inequality comparator.

Gt

A binary greater-than comparator.

Lt

A binary lower-than comparator.

Geq

A binary greater-than-or-equal comparator.

Leq

A binary lower-than-or-equal comparator.

And

A binary logical and operator.

Or

A binary logical or operator.

Not

A binary logical not operator.

Assign

A binary assignment operator.

AddAssign

A binary add-assign operator.

SubAssign

A binary subtract-assign operator.

MulAssign

A binary multiply-assign operator.

DivAssign

A binary divide-assign operator.

ModAssign

A binary modulo-assign operator.

ExpAssign

A binary exponentiate-assign operator.

AndAssign

A binary and-assign operator.

OrAssign

A binary or-assign operator.

Tuple

An n-ary tuple constructor.

Chain

An n-ary subexpression chain.

Const

Fields

value: Value

The value of the constant.

A constant value.

VariableIdentifierWrite

Fields

identifier: String

The identifier of the variable.

A write to a variable identifier.

VariableIdentifierRead

Fields

identifier: String

The identifier of the variable.

A read from a variable identifier.

FunctionIdentifier

Fields

identifier: String

The identifier of the function.

A function identifier.

Trait Implementations

impl Clone for Operator

fn clone(&self) -> Operator

Returns a copy 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 Display for Operator

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

Formats the value using the given formatter.

impl PartialEq<Operator> for Operator

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

This method tests for self and other values to be equal, and is used by ==.

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

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