Implementations

impl AssignmentOperator

pub fn is_assign(self) -> bool

Returns true for =.

pub fn is_logical(self) -> bool

Returns true for ’||=, &&=, and ??=`.

pub fn is_arithmetic(self) -> bool

Returns true for +=, -=, *=, /=, %=, and **=.

pub fn is_bitwise(self) -> bool

Returns true for |=, ^=, &=, <<=, >>=, and >>>=.

pub fn to_logical_operator(self) -> Option<LogicalOperator>

Get LogicalOperator corresponding to this AssignmentOperator.

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

Get BinaryOperator corresponding to this AssignmentOperator.

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

Get the string representation of this operator.

This is the same as how the operator appears in source code.

Trait Implementations

impl Clone for AssignmentOperator

fn clone(&self) -> AssignmentOperator

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 AssignmentOperator

type Cloned = AssignmentOperator

The type of the cloned object.

fn clone_in(&self, allocator: &'new_alloc Allocator) -> Self::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, ) -> Self::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 AssignmentOperator

fn content_eq(&self, other: &Self) -> 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 AssignmentOperator

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for AssignmentOperator

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

Create a dummy AssignmentOperator.

Does not allocate any data into arena.

impl PartialEq for AssignmentOperator

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