Struct pix_engine::vector::Vector

pub struct Vector<T = f64, const N: usize = 2>(/* private fields */);

A Euclidean Vector in N-dimensional space.

Also known as a geometric vector. A Vector has both a magnitude and a direction. The Vector struct, however, contains N values for each dimensional coordinate.

The magnitude and direction are retrieved with the mag and heading methods.

Some example uses of a Vector include modeling a position, velocity, or acceleration of an object or particle.

Vectors can be combined using vector math, so for example two Vectors can be added together to form a new Vector using let v3 = v1 + v2 or you can add one Vector to another by calling v1 += v2.

Please see the module-level documentation for examples.
