Struct bfkit::interp::Interpreter

pub struct Interpreter { /* fields omitted */ }

A Brainfuck interpreter that supports breakpoints.

Methods

impl Interpreter

pub fn new(code: Vec<BrainfuckInstruction>) -> Self

Creates a new Interpreter form some input program.

Arguments

• code - A sequence of BrainfuckInstructions to be interpreted.

pub fn set_breakpoint(&mut self, address: usize) -> Result<bool, String>

Sets a breakpoint at the specified code address.

Arguments

• address - The code address to set a breakpoint at.

pub fn delete_breakpoint(&mut self, address: usize) -> bool

Removes a breakpoint at the specified code address.

Arguments

• address - The code address to delete a breakpoint from.

pub fn run(&mut self) -> StopReason

Runs the Interpreter until either a breakpoint is hit or until the program has run to completion.

pub fn step(&mut self)

Executes a single BrainfuckInstruction.

pub fn get(&self, address: usize) -> Result<u8, String>

Reads a value from the tape at the specified address.

Arguments

• address - The tape address to read.

pub fn set(&mut self, address: usize, value: u8) -> Result<u8, String>

Writes a value to the tape at the specified address.

Arguments

• address - The tape address to write to.
• value - The value to write.

pub fn jump(&mut self, address: usize) -> Result<(), String>

Sets the instruction pointer to the specified code address.

Arguments

• address - The code address to jump to.

pub fn select(&mut self, address: usize) -> Result<(), String>

Sets the data pointer to the specified tape address.

Arguments

• address - The tape address to set the data pointer to.
