Implementations

impl Token

pub fn is_reserved_word(&self) -> bool

Indicates whether the token is a reserved word.

pub fn reserved_word_name(&self) -> Option<String>

Tests whether the token is a reserved word and returns its IdentifierName string.

pub fn compound_assignment(&self) -> Option<Operator>

Converts a compound assignment, a logical assignment, or a nullish coalescing assignment to an operator.

pub fn to_binary_operator(&self) -> Option<Operator>

Converts this token into a binary operator, excluding not instanceof, not in, and is not.

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Token

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

Formats the value using the given formatter.

impl PartialEq for Token

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToString for Token

fn to_string(&self) -> String

Converts the token into a readable string. Refer to the source code of this implementation for the possible return values. Updates to the parser shall not break existing programs that rely on the return values returned by this method.
