Struct Rect 

pub struct Rect {
    pub origin: Point,
    pub size: Size,
}

An axis-aligned rectangle defined by its top-left Point and Size.

Fields

origin: Point

Top-left corner.

size: Size

Width and height.

Implementations

impl Rect

pub const ZERO: Rect

A zero rectangle at the origin.

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

Construct a rectangle from explicit x, y, width, height.

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

Construct a rectangle from an origin and size.

pub fn left(&self) -> f32

Left edge (origin.x).

pub fn top(&self) -> f32

Top edge (origin.y).

pub fn right(&self) -> f32

Right edge (origin.x + width).

pub fn bottom(&self) -> f32

Bottom edge (origin.y + height).

pub fn width(&self) -> f32

Width in logical pixels.

pub fn height(&self) -> f32

Height in logical pixels.

pub fn center(&self) -> Point

Geometric centre of the rectangle.

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

Returns true if p lies within the rectangle (inclusive of the top/left edges, exclusive of the bottom/right edges).

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

Returns true if this rectangle shares any interior area with other.

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

Returns the overlapping rectangle, or None if the two do not overlap.

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

Returns the smallest rectangle enclosing both self and other.

pub fn deflate(&self, insets: Insets) -> Rect

Shrink the rectangle inward by insets (clamped to non-negative size).

pub fn inflate(&self, insets: Insets) -> Rect

Grow the rectangle outward by insets.

pub fn is_empty(&self) -> bool

Returns true if width or height is zero or negative.

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 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 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.
