Enum Operator 

pub enum Operator {
    Arithmetic(ArithmeticOperator),
    Assignment(AssignmentOperator),
    Bitwise(BitwiseOperator),
    Comparison(ComparisonOperator),
    Logical(LogicalOperator),
    Other(OtherOperator),
}

Any operator in the expression language.

A thin wrapper over the six family types, for code that handles operators generically. Reach for the family type directly when only one set applies.

Variants

Arithmetic(ArithmeticOperator)

An arithmetic operator.

Assignment(AssignmentOperator)

An assignment operator.

Bitwise(BitwiseOperator)

A bitwise operator.

Comparison(ComparisonOperator)

A comparison operator.

Logical(LogicalOperator)

A logical operator.

Other(OtherOperator)

A structural element.

Implementations

impl Operator

pub const fn symbol(self) -> &'static str

How the operator is written in an expression.

pub const fn class(self) -> OperatorClass

The family it belongs to.

pub const fn arity(self) -> Option<Arity>

How many operands it takes, for the families where that applies.

None for the structural elements: parentheses and comments do not take operands in the way an operator does.

pub const fn precedence(self) -> Option<u8>

Binding strength; lower binds tighter. None where it was not measured.

Trait Implementations

impl Clone for Operator

fn clone(&self) -> Operator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Operator

impl Debug for Operator

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

Formats the value using the given formatter.

impl Eq for Operator

impl Hash for Operator

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

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 PartialEq for Operator

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

Equality operator ==.

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

Inequality operator !=.
