Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].

impl<F: FullFloat> Deref for Direction2<F>

type Target = Vec2<F>

The resulting type after dereferencing.

fn deref(&self) -> &Vec2<F>

Dereferences the value.

impl<F: FullFloat> From<Direction2<F>> for Vec2<F>

fn from(v: Direction2<F>) -> Vec2<F>

Performs the conversion.

impl<F: FullFloat> From<Vec2<F>> for Direction2<F>

fn from(v: Vec2<F>) -> Direction2<F>

Performs the conversion.

impl<F: FullFloat> ApproxEq for Direction2<F>

type Flt = F

fn approx_eq(
    &self,
    other: &Self,
    epsilon: <F as ApproxEq>::Flt,
    ulps: <<F as ApproxEq>::Flt as Ulps>::U
) -> bool

This method tests for self and other values to be approximately equal using two methods: epsilon and ulps. If the values differ by less than the given epsilon, they will be considered equal. If the values differ by more than epsilon, but by less than the given ulps, they will also be considered equal. Otherwise they are unequal.

fn approx_ne(
    &self,
    other: &Self,
    epsilon: Self::Flt,
    ulps: <Self::Flt as Ulps>::U
) -> bool

This method tests for self and other values to be not approximately equal using two methods: epsilon and ulps. If the values differ by less than the given epsilon, they will be considered equal. If the values differ by more than epsilon, but by less than the given ulps, they will also be considered equal. Otherwise they are unequal.
