Struct kas::geom::DVec2

#[repr(C)]pub struct DVec2(pub f64, pub f64);

2D vector (double precision)

Usually used as either a coordinate or a difference of coordinates, but may have some other uses.

Vectors are partially ordered and support component-wise comparison via methods like lhs.lt(rhs). The PartialOrd trait is not implemented since it implements lhs ≤ rhs as lhs < rhs || lhs == rhs which is wrong for vectors (consider for lhs = (0, 1), rhs = (1, 0)).
