Struct gdk::Rectangle

#[repr(C)]
pub struct Rectangle {
    pub x: i32,
    pub y: i32,
    pub width: i32,
    pub height: i32,
}

Defines the position and size of a rectangle. It is identical to cairo_rectangle_int_t.

Fields

x: i32

y: i32

width: i32

height: i32

Implementations

impl Rectangle

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

Calculates the intersection of two rectangles. It is allowed for dest to be the same as either self or src2. If the rectangles do not intersect, dest’s width and height is set to 0 and its x and y values are undefined. If you are only interested in whether the rectangles intersect, but not in the intersecting area itself, pass None for dest.

src2

a Rectangle

Returns

true if the rectangles intersect.

dest

return location for the intersection of self and src2, or None

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

Calculates the union of two rectangles. The union of rectangles self and src2 is the smallest rectangle which includes both self and src2 within it. It is allowed for dest to be the same as either self or src2.

Note that this function does not ignore ‘empty’ rectangles (ie. with zero width or height).

src2

a Rectangle

Returns

dest

return location for the union of self and src2
