Enum Command

pub enum Command {
    IncrementCell,
    DecrementCell,
    MoveRight,
    MoveLeft,
    JumpForward,
    JumpBackward,
    OutputFromCell,

}

An executable HOHOHO! command.

Variants

IncrementCell

Increment memory cell at pointer.

DecrementCell

Decrement memory cell at pointer.

MoveRight

Move pointer to the right (or “forward” on the “tape”).

MoveLeft

Move pointer to the left (or “backward” on the “tape”).

JumpForward

Jump past the matching HoHoHO if the cell at the pointer is 0.

JumpBackward

Jump back to the matching HOHoHo if the cell at the pointer is not 0.

OutputFromCell

Output the character signified by the memory cell where the pointer is.

InputToCell

Input a character and store it in the memory cell where the pointer is.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Command

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

Formats the value using the given formatter.

impl Display for Command

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

Formats the value using the given formatter.

impl PartialEq for Command

fn eq(&self, other: &Command) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
