source

pub fn bounding_box(&self) -> Rect<f32, Space>

Returns a rectangle containing this region.

source

pub fn intersects(&self, rect: Rect<f32, Space>) -> bool

Returns true if this region has a non-empty intersection with the given rectangle.

source

pub fn is_empty(&self) -> bool

Returns true if this region is empty.

source

pub fn union_with(&mut self, other: &Region<Space>)

Modifies this region by including everything in the other region.
