Methods

impl<T: Float> Vector2<T>

pub fn unit_vector(direction: T) -> Self

pub fn normalise(self) -> Self

Normalises the vector

pub fn length(self) -> T

Returns the magnitude/length of the vector

pub fn length_squared(self) -> T

Returns the magnitude/length of the vector squared

pub fn direction(self) -> T

Returns direction the vector is pointing

pub fn direction_to(self, other: Self) -> T

Returns direction towards another vector

pub fn distance_to(self, other: Self) -> T

Returns the distance betweens two vectors

pub fn distance_to_squared(self, other: Self) -> T

Returns the distance betweens two vectors

pub fn is_any_nan(&self) -> bool

Returns true if either component is NaN.

pub fn is_any_infinite(&self) -> bool

Returns true if either component is positive or negative infinity.

pub fn is_all_finite(&self) -> bool

Returns true if both components are neither infinite nor NaN.

pub fn is_all_normal(&self) -> bool

Returns true if both components are neither zero, infinite, subnormal nor NaN.

impl<T> Vector2<T>

pub fn normal(self) -> Self where
    T: Neg<Output = T>, 

Returns the normal vector (aka. hat vector) of this vector i.e. a perpendicular vector

Not to be confused with normalise which returns a unit vector

Defined as (-y, x)

    T: Mul,
    <T as Mul>::Output: Add, 

Returns the dot product of two vectors

pub fn det(self, other: Self) -> <<T as Mul>::Output as Sub>::Output where
    T: Mul,
    <T as Mul>::Output: Sub, 

Returns the determinant of two vectors
