Provided Methods

fn add_f(self, scalar: F) -> Self

Add a scalar to both components of a point.

fn sub_f(self, scalar: F) -> Self

Subtract a scalar from both components of a point.

fn mul_f(self, scalar: F) -> Self

Multiply a point by a scalar.

fn abs(self) -> Self

Construct a point from the absolute components of self.

fn approx_eq(self, rhs: Self, epsilon: F) -> bool

Compare all components in self with rhs for approximate equality.

fn approx_eq_f(self, scalar: F, epsilon: F) -> bool

Compare all components in a point with a scalar for approximate equality.

fn round(self, n: usize) -> Self

Round the components of a point to N decimal places.

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

Returns a point-like containing the maximum values for each element of self and rhs.

In other words this computes [self.x().max(rhs.x), self.y().max(rhs.y())].

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

Returns a point-like containing the minimum values for each element of self and rhs.

In other words this computes [self.x.min(rhs.x), self.y.min(rhs.y)].

fn cross(self, rhs: Self) -> F

Compute the cross product of two points.

fn dot(self, rhs: Self) -> F

Computes the dot of self and rhs.

a · b = (x₁ · x₂) + (y₁ · y₂)

fn length(self) -> F

Computes the length of self.

c = √(a² + b²)

fn distance(self, rhs: Self) -> F

Computes the Euclidean distance between two points in space.

This works by relocating one point to the origin, then computing the length of the resulting vector.

c = √((x₂ - x₁)² + (y₂ - y₁)²)

fn partial_cmp(&self, other: &F) -> Option<Ordering>

fn lt(&self, other: &F) -> bool

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

fn le(self, other: &F) -> bool

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

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

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