Struct whitespacers::Interpreter

pub struct Interpreter<'a> { /* fields omitted */ }

A whitespace interpreter. This struct provides various strategies for interpreting a whitespace program.

Methods

impl<'a> Interpreter<'a>

fn new(
    program: &'a Program,
    options: Options,
    input: &'a mut BufRead + 'a,
    output: &'a mut Write + 'a
) -> Interpreter<'a>

Construct a new whitespace interpreter from a program, input stream and output stream with the specified options.

fn count_with_simple_state(&'a mut self) -> Result<usize, WsError>

Similar to Interpreter::interpret_with_simple_state but does not have bigint fallback and returns the amount of executed instructions on success.

fn interpret_with_simple_state(&'a mut self) -> Result<(), WsError>

The reference interpreter implementation. It uses simple data structures internally, falling back to bignum-based simple datastructures if values become too large.

fn interpret_with_fast_state(&'a mut self) -> Result<(), WsError>

Interprets the program with optimized data structures, falling back to bignum-based simple datastructures if values become too large.

fn interpret_with_bigint_state(&'a mut self) -> Result<(), WsError>

Interpret the program using only bignum-based simple datastructures. This is slow.
