Struct Rect 

pub struct Rect {
    pub x: f32,
    pub y: f32,
    pub w: f32,
    pub h: f32,
}

A rectangle: its corner x, y (the one with the smallest coordinates) and its size.

Fields

x: f32

y: f32

w: f32

h: f32

Implementations

impl Rect

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

pub const fn from_edges(x0: f32, y0: f32, x1: f32, y1: f32) -> Rect

The rectangle from x0, y0 to x1, y1 (x1 ≥ x0, y1 ≥ y0).

pub fn from_corners(a: Vec2, b: Vec2) -> Rect

The rectangle from corner a to corner b, in any order.

pub fn right(&self) -> f32

pub fn bottom(&self) -> f32

pub fn center(&self) -> Vec2

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

pub fn inset(&self, pad: [f32; 4]) -> Rect

The rect shrunk by pad (top, right, bottom, left — y down), never negative.

pub fn outset(&self, r: f32) -> Rect

Grown by r on every side.

pub fn translate(&self, d: Vec2) -> Rect

pub fn scale(&self, s: f32) -> Rect

Every coordinate times s.

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

The overlap of two rects; None when they don’t overlap.

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

pub fn around(points: impl IntoIterator<Item = Vec2>) -> Option<Rect>

The smallest rectangle around points; None for none.

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<(), Error>

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

Equality operator ==.

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

Inequality operator !=.

impl Schema for Rect

fn shape() -> Shape

What the format looks like.

fn read(v: &ValueRef<'_>, cx: &mut Reader<'_>) -> Option<Rect>

Reads v. Problems go to cx at its current path; None when the value couldn’t be read (the problem is in cx).

fn write(&self) -> Value

The value, as the format writes it.

fn absent() -> Option<Self>

The value of a field that isn’t there — None: the field is required.

fn skip(&self) -> bool

Whether a struct leaves this field out when writing it.
