Struct Rect 

pub struct Rect<T>
where
    T: NumAssign + Scalar + PartialOrd + Copy,
{
    pub position: Vector2<T>,
    pub size: Vector2<T>,
}

Fields

position: Vector2<T>

size: Vector2<T>

Implementations

impl<T> Rect<T>

where T: NumAssign + Scalar + PartialOrd + Copy,

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

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

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

pub fn contains(&self, pt: Vector2<T>) -> bool

pub fn push(&mut self, p: Vector2<T>)

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);
}

Trait Implementations

impl<T> Clone for Rect<T>

where T: NumAssign + Scalar + PartialOrd + Copy + Clone,

fn clone(&self) -> Rect<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for Rect<T>

where T: NumAssign + Scalar + PartialOrd + Copy + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Default for Rect<T>

where T: NumAssign + Scalar + PartialOrd + Copy,

fn default() -> Self

Returns the “default value” for a type.

impl<T> PartialEq for Rect<T>

where T: NumAssign + Scalar + PartialOrd + Copy + PartialEq,

fn eq(&self, other: &Rect<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Visit for Rect<T>

where T: NumAssign + Scalar + Visit + PartialOrd + Copy + 'static,

fn visit(&mut self, name: &str, visitor: &mut Visitor) -> VisitResult

impl<T> Copy for Rect<T>

where T: NumAssign + Scalar + PartialOrd + Copy + Copy,

impl<T> StructuralPartialEq for Rect<T>

where T: NumAssign + Scalar + PartialOrd + Copy,
