Expand description

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

A constant value.

Show fields

Fields of Const

value: Value

The value of the constant.

VariableIdentifier

A variable identifier.

Show fields

Fields of VariableIdentifier

identifier: String

The identifier of the variable.

FunctionIdentifier

A function identifier.

Show fields

Fields of FunctionIdentifier

identifier: String

The identifier of the function.
