Implementations

impl Operator

pub fn kinds() -> Vec<Operator>

pub fn kinds_to_string() -> Vec<String>

impl Operator

pub fn precedence(&self) -> u8

Returns the precedence level of the operator.

Higher precedence values indicate that the operator should be evaluated first.

pub fn is_left_associative(&self) -> bool

Determines if the operator is left associative.

Left associative operators are evaluated from left to right. For example, a - b - c is evaluated as (a - b) - c.

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

Formats the value using the given formatter.

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 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 Copy for Operator

impl StructuralPartialEq for Operator
