Struct Rect 

pub struct Rect {
    pub x: f32,
    pub y: f32,
    pub width: f32,
    pub height: f32,
}

Rect is an axis-aligned rectangle in Valo’s y-down coordinate system.

Fields

x: f32

x is the left edge.

y: f32

y is the top edge.

width: f32

width is the horizontal extent.

height: f32

height is the vertical extent.

Implementations

impl Rect

pub const EVERYTHING: Rect

EVERYTHING is the conservative bound used when content cannot be bounded.

pub const fn new(x: f32, y: f32, width: f32, height: f32) -> Self

new creates a rectangle from its top-left origin and size.

pub fn from_ltrb(l: f32, t: f32, r: f32, b: f32) -> Self

from_ltrb creates a rectangle from its left, top, right, and bottom edges.

pub fn from_origin_size(origin: Point, size: Size) -> Self

from_origin_size creates a rectangle from an origin and size.

pub fn right(&self) -> f32

right returns the x-coordinate of the right edge.

pub fn bottom(&self) -> f32

bottom returns the y-coordinate of the bottom edge.

pub fn origin(&self) -> Point

origin returns the top-left point.

pub fn size(&self) -> Size

size returns the rectangle’s width and height.

pub fn is_empty(&self) -> bool

is_empty reports whether either extent is nonpositive.

pub fn union(&self, other: &Rect) -> Rect

union returns the smallest rectangle containing both rectangles.

Empty rectangles act as the identity.

pub fn intersect(&self, other: &Rect) -> Option<Rect>

intersect returns the overlapping area or None when there is none.

pub fn intersects(&self, other: &Rect) -> bool

intersects reports whether the rectangles overlap with positive area.

pub fn contains(&self, p: Point) -> bool

contains reports whether a point lies within the half-open rectangle.

Left and top edges are included; right and bottom edges are excluded.

pub fn contains_inclusive(&self, p: Point) -> bool

contains_inclusive reports whether a point lies within or on every edge.

pub fn expand(&self, d: f32) -> Rect

expand moves every edge outward by d.

Negative values contract the rectangle.

pub fn corners(&self) -> [Point; 4]

corners returns corners clockwise from the top-left.
