Implementations

impl TokenKind

pub fn is_keyword(&self) -> bool

Check if this token is a keyword

pub fn can_start_expression(&self) -> bool

Check if this token can start an expression

pub fn produces_value(&self) -> bool

Check if this token produces a value (for regex vs division disambiguation)

Trait Implementations

impl Clone for TokenKind

fn clone(&self) -> TokenKind

Returns a duplicate 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 PartialEq for TokenKind

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