Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

impl<T> Index<(Axis, Order)> for DirectionMap<T>

type Output = T

The returned type after indexing.

fn index(&self, (axis, order): (Axis, Order)) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<T> Index<Direction> for DirectionMap<T>

type Output = T

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl<T> IndexMut<(Axis, Order)> for DirectionMap<T>

fn index_mut(&mut self, (axis, order): (Axis, Order)) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl<T> IndexMut<Direction> for DirectionMap<T>

fn index_mut(&mut self, index: Direction) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl<T: Ord> Ord for DirectionMap<T>

fn cmp(&self, other: &DirectionMap<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for DirectionMap<T>

fn eq(&self, other: &DirectionMap<T>) -> 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.

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
