Struct Parser 

pub struct Parser { /* private fields */ }

Parser for building Scheme values from tokens

Corresponds to OpenJade’s SchemeParser::get* methods.

Usage

let parser = Parser::new("(+ 1 2)");
let expr = parser.parse().unwrap();

Implementations

impl Parser

pub fn new(input: &str) -> Self

Create a new parser from source code

pub fn parse(&mut self) -> ParseResult<Value>

Parse a single S-expression

Returns Ok(Value) on success, Err(ParseError) on failure.

pub fn peek_token(&mut self) -> ParseResult<&Token>

Peek at the next token without consuming it

Returns Ok(&Token) if successful, Err(ParseError) on tokenizer error. This is useful for checking if we’re at EOF before attempting to parse.

pub fn current_position(&self) -> Position

Get the current position in the source code

Returns the position of the last token consumed by the parser. Useful for error reporting.

pub fn parse_all(&mut self) -> ParseResult<Vec<Value>>

Parse all S-expressions in input

Returns a list of all top-level expressions.
