fn intersects_shape(&self, other: &(dyn Shape + 'static)) -> Option<bool>

Returns

impl IntersectsShape for Circle

fn intersects_rect(&self, rect: &Rect) -> bool

Returns true if rect intersects self

impl PartialEq for Circle

fn eq(&self, other: &Circle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
