Implementations

impl Token

pub fn display_name(&self) -> String

Human-readable name for error messages. Avoids exposing raw Rust Debug format like IntLit(42) to end users.

pub fn keyword_str(&self) -> Option<&'static str>

The lowercase source spelling of this token when it is a reserved keyword (or built-in literal word), or None for identifiers, literals, operators, and delimiters. Inverts the lexer’s word→token table so the parser can tell a caller which reserved word collided with an identifier position and how to quote it (`type`).

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a duplicate 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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Token
