Struct math2d::Rectf

#[repr(C)]
pub struct Rectf {
    pub left: f32,
    pub top: f32,
    pub right: f32,
    pub bottom: f32,
}

Represents a rectangle defined by the coordinates of the upper-left corner (left, top) and the coordinates of the lower-right corner (right, bottom).

Fields

left: f32

The x-coordinate of the left edge of the rectangle.

top: f32

The y-coordinate of the top edge of the rectangle.

right: f32

The x-coordinate of the right edge of the rectangle.

bottom: f32

The y-coordinate of the bottom edge of the rectangle.

Methods

impl Rectf

pub const INFINITE: Rectf

A rect that holds the entire real space

pub fn new(left: f32, top: f32, right: f32, bottom: f32) -> Rectf

Constructs the rectangle from components.

pub fn from_points(p1: impl Into<Point2f>, p2: impl Into<Point2f>) -> Rectf

Constructs a rectangle that will encompass all of the axis-aligned space between the two provided points.

pub fn from_center_size(
    center: impl Into<Point2f>,
    size: impl Into<Sizef>
) -> Rectf

Constructs a rectangle given its desired center point and desired width and height.

pub fn from_center_half_extent(
    center: impl Into<Point2f>,
    half_extents: impl Into<Vector2f>
) -> Rectf

Constructs a rectangle given its desired center and the desired distance from the center to the corners.

pub fn to_i32(&self) -> Recti

Converts this rectangle's components to signed integers. Truncates values, perform manual rounding if you would like a different behavior.

pub fn to_u32(&self) -> Rectu

Converts the components of the rectangle to unsigned integers. Beware this conversion if the components could be negative, you will experience unsigned casting underflow.

pub fn rounded(&self) -> Rectf

Rounds the components to the nearest integers, rounding half-way values away from zero.

pub fn size(&self) -> Sizef

Gets the width and height of this rectangle.

pub fn center(&self) -> Point2f

Gets the center point of this rectangle.

pub fn half_extent(&self) -> Vector2f

Gets the half-extent of the rectangle i.e. the vector from the center to the most-positive corner.

pub fn corner(&self, corner: RectCorner) -> Point2f

Get the point of the specified corner.

pub fn contains_point(&self, point: impl Into<Point2f>) -> bool

Determines if the specified point is located inside the rectangle.

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

Determines if two rects overlap at all

pub fn normalized(self) -> Self

Normalizes the rectangle to enforce the invariants left < right and top < bottom.

pub fn translated_by(self, translation: impl Into<Vector2f>) -> Self

Translates the rectangle by the given vector.

pub fn expanded_by(self, thickness: impl Into<Thicknessf>) -> Self

Expands the rectangle by the given margin.

pub fn shrunken_by(self, thickness: impl Into<Thicknessf>) -> Self

Shrinks the rectangle by the given margin.

pub fn combined_with(&self, other: impl Into<Rectf>) -> Self

Constructs a rectangle that contains both rectangles. Normalizes both arguments before performing the operation.
