Type Definition bf::ast::Program

type Program = [Statement];

A BF program is represented as a slice of statements. The slice will typically be boxed.

Trait Implementations

impl Interpretable for Program

fn interpret_state<R: Read, W: Write>(     &self,     state: State,     input: R,     output: W ) -> BfResult<()>

Interprets a program against the given state.

fn interpret<R: Read, W: Write>(     &self,     size: Option<usize>,     input: R,     output: W ) -> BfResult<()>

Interprets a program. If the given size is None, the default memory size.

fn interpret_stdin(&self, size: Option<usize>) -> BfResult<()>

Interprets a program using stdin and stdout for input and output.

fn interpret_memory(     &self,     size: Option<usize>,     input: &[u8] ) -> BfResult<Vec<u8>>

Interprets a program from memory, returning a vector of its output.

impl RleCompilable for Program

fn with_ast<F, R>(&self, k: F) -> R where     F: FnOnce(&Program) -> R,

Convert the given program to unoptimized AST to prepare for run-length encoding.

Important traits for Box<R>

impl<R> Read for Box<R> where
    R: Read + ?Sized, impl<W> Write for Box<W> where
    W: Write + ?Sized, impl<I> Iterator for Box<I> where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

fn rle_compile(&self) -> Box<Program>

Run-length encode the given program.
