Struct Machine

pub struct Machine { /* private fields */ }

An instance of an Intcode virtual machine.

Implementations

impl Machine

pub fn new() -> Machine

Constructs a new machine with the initial state:

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

pub fn with_program(program: &[isize]) -> Machine

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, input: Option<isize>) -> Result<(), Exit>

Executes a single instruction.

pub fn resume(&mut self, input: Option<isize>) -> Exit

Runs the program until the first error is encountered.

pub fn run<I, O>(&mut self, input: I, output: O) -> Exit

where I: IntoIterator<Item = isize>, O: FnMut(isize),

Runs the program using the given I/O interfaces.

pub fn spawn<I, O>(self, input: I, output: O) -> JoinHandle<(Machine, Exit)>

where I: IntoIterator<Item = isize> + Send + 'static, O: FnMut(isize) + Send + 'static,

impl Debug for Machine

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
