Expand description

Specifies geometric operations for vectors. This is only implemented for 2-dimensional and 3-dimensional vectors.

Required Methods§

source

fn angle(self, other: Self) -> Rad<Self::Scalar>

The angle between the vector and other, in radians.

Provided Methods§

source

fn is_perpendicular(self, other: Self) -> bool

Returns true if the vector is perpendicular (at right angles) to the other vector.

source

fn length2(self) -> Self::Scalar

Returns the squared length of the vector. This does not perform an expensive square root operation like in the length method and can therefore be more efficient for comparing the lengths of two vectors.
