Implementations

impl UnaryOperator

pub fn is_arithmetic(self) -> bool

Returns true if this operator is a unary arithmetic operator.

pub fn is_not(self) -> bool

Returns true if this operator is a LogicalNot.

pub fn is_bitwise(self) -> bool

Returns true if this operator is a bitwise operator.

pub fn is_typeof(self) -> bool

Returns true if this is the void operator.

pub fn is_void(self) -> bool

Returns true if this is the void operator.

pub fn is_delete(self) -> bool

Returns true if this is the delete operator.

pub fn is_keyword(self) -> bool

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

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

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

Trait Implementations

impl Clone for UnaryOperator

fn clone(&self) -> UnaryOperator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'new_alloc> CloneIn<'new_alloc> for UnaryOperator

type Cloned = UnaryOperator

The type of the cloned object.

fn clone_in( &self, allocator: &'new_alloc Allocator, ) -> <UnaryOperator 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, ) -> <UnaryOperator 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 UnaryOperator

fn content_eq(&self, other: &UnaryOperator) -> 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 UnaryOperator

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for UnaryOperator

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

Create a dummy UnaryOperator.

Does not allocate any data into arena.

impl ESTree for UnaryOperator

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

where S: Serializer,

impl Hash for UnaryOperator

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 UnaryOperator

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