Struct Rect 

#[repr(C)]
pub struct Rect {
    pub x: f32,
    pub y: f32,
    pub w: f32,
    pub h: f32,
}

An axis-aligned rectangle defined by its top-left corner, width, and height.

Uses the screen-space convention: Y increases downward.

Fields

x: f32

X coordinate of the top-left corner.

y: f32

Y coordinate of the top-left corner.

w: f32

Width of the rectangle.

h: f32

Height of the rectangle.

Implementations

impl Rect

pub const fn new(x: f32, y: f32, w: f32, h: f32) -> Self

Create a new rectangle from position and size.

pub const fn from_min_max(min: Vec2, max: Vec2) -> Self

Create a rectangle from min and max corner points.

pub const fn centered(center: Vec2, size: Vec2) -> Self

Create a rectangle centered at center with the given size.

pub fn pos(self) -> Vec2

Top-left corner position.

pub fn size(self) -> Vec2

Size of the rectangle.

pub fn center(self) -> Vec2

Center point of the rectangle.

pub fn max(self) -> Vec2

Bottom-right corner (exclusive).

pub fn top_right(self) -> Vec2

Top-right corner.

pub fn bottom_left(self) -> Vec2

Bottom-left corner.

pub fn contains(self, point: Vec2) -> bool

Check if the rectangle contains a point.

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

Check if this rectangle fully contains another.

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

Check if two rectangles overlap (AABB intersection test).

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

Compute the intersection rectangle, or None if they don’t overlap.

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

Compute the union rectangle that covers both.

pub fn inflated(self, amount: f32) -> Rect

Inflate the rectangle by amount on all sides.

pub fn deflated(self, amount: f32) -> Rect

Shrink the rectangle by amount on all sides.

pub fn scaled(self, scale: Vec2) -> Rect

Scale the rectangle around its center.

pub fn with_center(self, center: Vec2) -> Rect

Move the rectangle so its center is at center.

pub fn translated(self, offset: Vec2) -> Rect

Translate the rectangle by an offset.

pub fn closest_point(self, point: Vec2) -> Vec2

Closest point inside the rectangle to the given point.

pub fn area(self) -> f32

Area of the rectangle.

pub fn perimeter(self) -> f32

Perimeter of the rectangle.

pub fn aspect_ratio(self) -> f32

Aspect ratio (width / height).

Trait Implementations

impl Clone for Rect

fn clone(&self) -> Rect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Rect

impl Debug for Rect

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

Formats the value using the given formatter.

impl Default for Rect

fn default() -> Rect

Returns the “default value” for a type.

impl Display for Rect

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

Formats the value using the given formatter.

impl PartialEq for Rect

fn eq(&self, other: &Rect) -> 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.
