Enum LeftAssociativeOperator 

pub enum LeftAssociativeOperator {
    Add,
    Subtract,
    Multiply,
    Divide,
    Power,
    Root,
}

A left-associative operator is an operator that requires a left and right of the equation (i.e. +).

Variants

Add

The addition operator.

Subtract

The subtraction operator.

Multiply

The multiplication operator.

Divide

The division operator.

Power

The exponentiation operator.

Root

The root operator. (not used)

Implementations

impl LeftAssociativeOperator

pub fn is_of_order(&self, order: &u8) -> bool

Checks weather the order of the operator is correct. (for pemdas)

pub fn eval(&self, lhs: f64, rhs: f64) -> f64

Returns the value of the operator given the left and right values.

Trait Implementations

impl Clone for LeftAssociativeOperator

fn clone(&self) -> LeftAssociativeOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LeftAssociativeOperator

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

Formats the value using the given formatter.

impl From<LeftAssociativeOperator> for Item

fn from(val: LeftAssociativeOperator) -> Self

Converts to this type from the input type.

impl From<LeftAssociativeOperator> for Operator

fn from(val: LeftAssociativeOperator) -> Self

Converts to this type from the input type.

impl PartialEq for LeftAssociativeOperator

fn eq(&self, other: &LeftAssociativeOperator) -> 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.
