Struct riddle_math::Vector2

#[repr(C)]pub struct Vector2<T> {
    pub x: T,
    pub y: T,
}

A basic 2d vector, supporting a small selection of operations

Supported operations (depending on element type):

• Add
• Subtract
• Mul
• Neg (where T: std::ops::Neg)
• Converting to vectors of other element types

Example

let v = vec2(1,2);
assert_eq!(vec2(2, 4), v + v);
assert_eq!(vec2(0, 0), v - v);
assert_eq!(vec2(3, 6), v * 3);
assert_eq!(vec2(-1, -2), -v);

assert_eq!(vec2(1.0, 2.0), v.convert());

Fields

x: T

y: T
