Implementations

impl TokenKind

pub const fn boolean_literal(lit: bool) -> Self

Creates a BooleanLiteral token kind.

Creates a Punctuator token type.

pub const fn string_literal(lit: Sym, escape_sequence: EscapeSequence) -> Self

Creates a StringLiteral token type.

pub const fn template_middle(template_string: TemplateString) -> Self

Creates a TemplateMiddle token type.

Trait Implementations

impl Clone for TokenKind

fn clone(&self) -> TokenKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenKind

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

Formats the value using the given formatter.

impl From<(Keyword, bool)> for TokenKind

fn from(kw: (Keyword, bool)) -> Self

Converts to this type from the input type.

impl From<Numeric> for TokenKind

fn from(num: Numeric) -> Self

Converts to this type from the input type.

impl From<Punctuator> for TokenKind

fn from(punc: Punctuator) -> Self

Converts to this type from the input type.

impl From<bool> for TokenKind

fn from(oth: bool) -> Self

Converts to this type from the input type.

impl PartialEq for TokenKind

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