Struct Rect

pub struct Rect { /* private fields */ }

A rectangle defined by left, top, right and bottom edges.

Can have zero width and/or height. But not a negative one.

Guarantees

• All values are finite.
• Left edge is <= right.
• Top edge is <= bottom.
• Width and height are <= f32::MAX.

Implementations

impl Rect

pub fn from_ltrb(left: f32, top: f32, right: f32, bottom: f32) -> Option<Rect>

Creates new Rect.

pub fn from_xywh(x: f32, y: f32, w: f32, h: f32) -> Option<Rect>

Creates new Rect.

pub fn left(&self) -> f32

Returns the left edge.

pub fn top(&self) -> f32

Returns the top edge.

pub fn right(&self) -> f32

Returns the right edge.

pub fn bottom(&self) -> f32

Returns the bottom edge.

pub fn x(&self) -> f32

Returns rect’s X position.

pub fn y(&self) -> f32

Returns rect’s Y position.

pub fn width(&self) -> f32

Returns rect’s width.

pub fn height(&self) -> f32

Returns rect’s height.

pub fn round(&self) -> Option<IntRect>

Converts into an IntRect by adding 0.5 and discarding the fractional portion.

Width and height are guarantee to be >= 1.

pub fn round_out(&self) -> Option<IntRect>

Converts into an IntRect rounding outwards.

Width and height are guarantee to be >= 1.

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

Returns an intersection of two rectangles.

Returns None otherwise.

pub fn from_points(points: &[Point]) -> Option<Rect>

Creates a Rect from Point array.

Returns None if count is zero or if Point array contains an infinity or NaN.

pub fn inset(&self, dx: f32, dy: f32) -> Option<Rect>

Insets the rectangle by the specified offset.

pub fn outset(&self, dx: f32, dy: f32) -> Option<Rect>

Outsets the rectangle by the specified offset.

pub fn transform(&self, ts: Transform) -> Option<Rect>

Transforms the rect using the provided Transform.

This method is expensive.

pub fn bbox_transform(&self, bbox: NonZeroRect) -> Rect

Applies a bounding box transform.

pub fn to_non_zero_rect(&self) -> Option<NonZeroRect>

Converts into NonZeroRect.

Trait Implementations

impl Clone for Rect

fn clone(&self) -> Rect

Returns a copy 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<(), Error>

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.
