Implementations

impl Dir

pub const fn opposite(self) -> Self

Returns the opposite direction.

Changes the direction to its opposite.

pub const fn rotate_ccw(self) -> Self

Returns the next direction in counter-clockwise rotation.

pub const fn rotate_ccw_mut(&mut self)

Changes the direction to the next one in counter-clockwise rotation.

pub const fn rotate_cw(self) -> Self

Returns the next direction in clockwise rotation.

pub const fn rotate_cw_mut(&mut self)

Changes the direction to the next one in clockwise rotation.

Trait Implementations

impl Clone for Dir

fn clone(&self) -> Dir

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dir

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

Formats the value using the given formatter.

impl From<Dir> for usize

fn from(value: Dir) -> Self

Converts to this type from the input type.

impl From<usize> for Dir

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Hash for Dir

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> Index<Dir> for [T]

type Output = T

The returned type after indexing.

fn index(&self, index: Dir) -> &Self::Output

Performs the indexing (container[index]) operation.

impl PartialEq for Dir

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