Struct Parser 

pub struct Parser<'a> { /* private fields */ }

Parser state — wraps a Lexer and builds arena-allocated AST nodes.

The parser consumes tokens from the lexer and constructs S-expression trees in the arena. It handles list building, dotted pairs, quote desugaring, and vector literals.

Implementations

impl<'a> Parser<'a>

pub fn new(input: &'a str) -> Parser<'a>

Create a new parser

pub fn from_bytes(input: &'a [u8]) -> Parser<'a>

Create from bytes

pub fn lexer(&self) -> &Lexer<'a>

Get a reference to the underlying lexer

pub fn lexer_mut(&mut self) -> &mut Lexer<'a>

Get a mutable reference to the underlying lexer

pub fn parse<const N: usize>( &mut self, lisp: &Lisp<N>, ) -> Result<ArenaIndex, ParseError>

Parse a single expression

pub fn has_more(&mut self) -> bool

Check if there’s more input (after whitespace)

pub fn position(&self) -> (usize, usize)

Get current position for error reporting
