Implementations

impl BinaryOperator

pub fn is_equality(self) -> bool

Returns true for inequality or inequality operarors

pub fn is_compare(self) -> bool

Returns true for logical comparison operators

pub fn is_arithmetic(self) -> bool

Returns true for arithmetic operators

pub fn is_multiplicative(self) -> bool

Returns true for multiplication (*), division (/), and remainder (%) operators

pub fn is_relational(self) -> bool

Returns true for object relation operators

pub fn is_in(self) -> bool

Returns true if this is an In operator.

pub fn is_instance_of(self) -> bool

Returns true if this is an In operator.

pub fn is_bitwise(self) -> bool

Returns true for any bitwise operator

pub fn is_bitshift(self) -> bool

Returns true for any bitshift operator

pub fn is_numeric_or_string_binary_operator(self) -> bool

Returns true for any numeric or string binary operator

pub fn is_keyword(self) -> bool

Returns true if this operator is a keyword instead of punctuation.

pub fn compare_inverse_operator(self) -> Option<BinaryOperator>

Try to get the operator that performs the inverse comparison operation. None if this is not a comparison operator.

pub fn equality_inverse_operator(self) -> Option<BinaryOperator>

Try to get the operator that performs the inverse equality operation. None if this is not an equality operator.

pub fn to_assignment_operator(self) -> Option<AssignmentOperator>

Get AssignmentOperator corresponding to this BinaryOperator.

pub fn as_str(self) -> &'static str

The string representation of this operator as it appears in source code.

pub fn lower_precedence(self) -> Precedence

Get the operator that has a lower precedence than this operator by a single level. Use BinaryOperator::precedence to get the operator with a higher precedence.

Trait Implementations

impl Clone for BinaryOperator

fn clone(&self) -> BinaryOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'new_alloc> CloneIn<'new_alloc> for BinaryOperator

type Cloned = BinaryOperator

The type of the cloned object.

fn clone_in( &self, allocator: &'new_alloc Allocator, ) -> <BinaryOperator as CloneIn<'new_alloc>>::Cloned

Clone self into the given allocator. allocator may be the same one that self is already in.

fn clone_in_with_semantic_ids( &self, allocator: &'new_alloc Allocator, ) -> <BinaryOperator as CloneIn<'new_alloc>>::Cloned

Almost identical as clone_in, but for some special type, it will also clone the semantic ids. Please use this method only if you make sure semantic info is synced with the ast node.

impl ContentEq for BinaryOperator

fn content_eq(&self, other: &BinaryOperator) -> bool

This method tests for contents of self and other to be equal.

fn content_ne(&self, other: &Self) -> bool

This method tests for contents of self and other not to be equal. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Debug for BinaryOperator

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for BinaryOperator

fn dummy(allocator: &'a Allocator) -> BinaryOperator

Create a dummy BinaryOperator.

Does not allocate any data into arena.

impl ESTree for BinaryOperator

fn serialize<S>(&self, serializer: S)

where S: Serializer,

impl GetPrecedence for BinaryOperator

fn precedence(&self) -> Precedence

impl Hash for BinaryOperator

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

where __H: Hasher,

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 BinaryOperator

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