pub const DOWN: Self = _

The vector pointing one pixel down.

pub const fn new(dx: i32, dy: i32) -> Self

Creates a new vector.

pub fn random_cardinal_with(rng: &mut impl Rng) -> Self

Trait Implementations

impl Add<Delta> for Pos

type Output = Pos

The resulting type after applying the + operator.

fn add(self, rhs: Delta) -> Self

Performs the + operation.

impl Add for Delta

type Output = Delta

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self

Performs the + operation.

impl AddAssign<Delta> for Pos

fn add_assign(&mut self, rhs: Delta)

Performs the += operation.

impl Clone for Delta

fn clone(&self) -> Delta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Delta

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

Formats the value using the given formatter.

impl Display for Delta

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

Formats the value using the given formatter.

impl Hash for Delta

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 Mul<Delta> for Rotation

type Output = Delta

The resulting type after applying the * operator.

fn mul(self, rhs: Delta) -> Delta

Performs the * operation.

impl Neg for Delta

type Output = Delta

The resulting type after applying the - operator.

fn neg(self) -> Self

Performs the unary - operation.

impl PartialEq for Delta

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Sub<Delta> for Pos

type Output = Pos

The resulting type after applying the - operator.

fn sub(self, rhs: Delta) -> Self

Performs the - operation.

impl Sub for Delta

type Output = Delta

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self

Performs the - operation.

impl SubAssign<Delta> for Pos

fn sub_assign(&mut self, rhs: Delta)

Performs the -= operation.

impl Copy for Delta

impl Eq for Delta

impl StructuralPartialEq for Delta
