Implementations

impl Rectangle

pub fn to_device_coordinates(self, viewport: Rectangle) -> Rectangle

Convert a rectangle to device coordinates ([-1.0, 1.0]) using a Viewport. (-1, -1) is the top left corner (0, 0), where (1, 1) is the bottom right corner (viewport.width(), viewport.height()).

pub fn zero() -> Rectangle

Return a zero size rectangle

pub fn from_wh(w: f32, h: f32) -> Rectangle

Construct a new rectangle with (0, 0) as (left, top), and w, h as (right, bottom)

pub fn from_xywh(x: f32, y: f32, w: f32, h: f32) -> Rectangle

Construct a new rectangle from a position and a size

pub fn point_inside(&self, x: f32, y: f32) -> bool

Returns true when the queried point is inside the rectangle

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

Returns the rectangle that is covered both by self and other. None is returned if the rectangles do not overlap.

pub fn pt(&self, x: f32, y: f32) -> [f32; 2]

Return a point within this rectangle. The point should be in [0, 1] range.

pub fn round(self) -> Rectangle

Return a rectangle with all fields rounded

pub fn translate(&self, x: f32, y: f32) -> Rectangle

Apply a translation the the rectangle

pub fn grow(&self, w: f32, h: f32) -> Rectangle

Increase the size of the rectangle on the right and bottom side.

pub fn inset(&self, x: f32, y: f32) -> Option<Rectangle>

Decrease the size of the rectangle on all sides

pub fn outset(&self, x: f32, y: f32) -> Rectangle

Grow the rectangle on all sides

pub fn size(&self) -> Rectangle

Return a rectangle with the same size, but positioned at the origin

pub fn width(&self) -> f32

The width of the rectangle

pub fn height(&self) -> f32

The height of the rectangle

pub fn after_margin(self, margin: Rectangle) -> Rectangle

Apply a margin to the rectangle

pub fn after_padding(self, padding: Rectangle) -> Rectangle

Apply padding to the rectangle

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

Return the smallest rectangle that covers both self and other
