Rect

A (non-empty) rectangle.

The width and height of a Rect must always be strictly positive (never zero). In cases where empty rects may need to represented, it is recommended to use Option<Rect>, with None representing an empty rectangle (see, for example, the output of the intersection method).

Create New Rect

The width and height are clamped to ensure that the right and bottom sides of the rectangle does not exceed i32::MAX (the value 2147483647, the maximal positive size of an i32). This means that the rect size will behave oddly if you move it very far to the right or downwards on the screen.

Rects must always be non-empty, so a width and/or height argument of 0 will be replaced with 1.

pub fn new(x: i32, y: i32, width: u32, height: u32) -> Rect

Draw Rect

To draw the Rect on a Canvas, use draw_rect here. Note that this only draws an outline of a rect, to fill it, use fill_rect.

If Rectangle Contains Point

Sometimes you want to check if a rectangle contains a certain point, for example when checking if a user clicks within a button. To do so, simply use the contains_point method:

pub fn contains_point<P>(&self, point: P) -> bool
    where
        P: Into<(i32, i32)>,
