Struct intcodeint::Machine

pub struct Machine<I, O> { /* fields omitted */ }

An instance of an Intcode virtual machine.

Methods

impl<I, O> Machine<I, O> where
    I: Iterator<Item = isize>,
    O: FnMut(isize), 

pub fn new(input: I, output: O) -> Machine<I, O>

Constructs a new machine with the given I/O callbacks and the initial state:

• empty mem;
• ip pointing to zero;
• base set at zero.

pub fn mem(&self) -> &[isize]

An immutable view into the virtual machine's memory.

pub fn mem_mut(&mut self) -> &mut [isize]

A mutable view into the virtual machine's memory.

pub fn reserve(&mut self, size: usize)

Ensures that memory locations 0..size are valid, extending memory with zeroes if needed.

pub fn copy(&mut self, start: usize, values: &[isize])

Copies the given slice into memory at the given location.

pub fn step(&mut self) -> Result<(), Error>

Executes a single instruction.

pub fn run(&mut self) -> Error

Runs the program until the first error is encountered.
