Enum Move 

pub enum Move {
    Left,
    Right,
    None,
}

Move is a part of the crate::instruction::Tail and it’s used for tape shift direction determining by crate::state::Configuration. For any others structs direction value have no matter.

Turing Machine RS can works only with 1 dimension tape. That’s why Move enumeration contains two directions variant: Move::Left, Move::Right.

Istead of using Option, this enumeration provides one more variant - Move::None.

Variants

Left

Right

None

Trait Implementations

impl Clone for Move

fn clone(&self) -> Move

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Move

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

Formats the value using the given formatter.

impl Display for Move

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

Formats the value using the given formatter.

impl PartialEq for Move

fn eq(&self, other: &Move) -> 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.
