Struct Rect

pub struct Rect<T>where
    T: NumAssign + Scalar + PartialOrd + Copy,{
    pub position: Matrix<T, Const<nalgebra::::base::dimension::U2::{constant#0}>, Const<1>, ArrayStorage<T, 2, 1>>,

Implementations§

impl<T> Rect<T>
where T: NumAssign + Scalar + PartialOrd + Copy,

pub fn new(x: T, y: T, w: T, h: T) -> Rect<T>

pub fn inflate(&self, dw: T, dh: T) -> Rect<T>

pub fn deflate(&self, dw: T, dh: T) -> Rect<T>

pub fn contains( &self, pt: Matrix<T, Const<nalgebra::::base::dimension::U2::{constant#0}>, Const<1>, ArrayStorage<T, 2, 1>>, ) -> bool

Extends rect to contain given point.

§Notes

To build bounding rectangle you should correctly initialize initial rectangle:


let vertices = [Vector2::new(1.0, 2.0), Vector2::new(-3.0, 5.0)];

// This is important part, it must have "invalid" state to correctly
// calculate bounding rect. Rect::default will give invalid result!
let mut bounding_rect = Rect::new(f32::MAX, f32::MAX, 0.0, 0.0);

for &v in &vertices {
    bounding_rect.push(v);
}
