Struct Ring 

pub struct Ring<P>
where
    P: Primitive2d,
{
    pub outer_shape: P,
    pub inner_shape: P,
}

A 2D shape representing the ring version of a base shape.

The inner_shape forms the “hollow” of the outer_shape.

The resulting shapes are rings or hollow shapes. For example, a circle becomes an annulus.

Warning

The outer_shape must contain the inner_shape for the generated meshes to be accurate.

If there are vertices in the inner_shape that escape the outer_shape (for example, if the inner_shape is in fact larger), it may result in incorrect geometries.

Fields

outer_shape: P

The outer shape

inner_shape: P

The inner shape (the same shape of a different size)

Implementations

impl<P> Ring<P>

where P: Primitive2d,

pub const fn new(outer_shape: P, inner_shape: P) -> Ring<P>

Create a new Ring from a given outer_shape and inner_shape.

If the primitive implements Inset and you would like a uniform thickness, consider using ToRing::to_ring

impl<P> Ring<P>

where P: Primitive2d + Clone + Inset,

pub fn from_primitive_and_thickness(primitive: P, thickness: f32) -> Ring<P>

Generate a Ring from a given primitive and a thickness.

Trait Implementations

impl<P> Bounded2d for Ring<P>

where P: Bounded2d + Primitive2d,

fn aabb_2d(&self, isometry: impl Into<Isometry2d>) -> Aabb2d

Get an axis-aligned bounding box for the shape translated and rotated by the given isometry.

fn bounding_circle(&self, isometry: impl Into<Isometry2d>) -> BoundingCircle

Get a bounding circle for the shape translated and rotated by the given isometry.

impl<T> BoundedExtrusion for Ring<T>

where T: BoundedExtrusion,

fn extrusion_aabb_3d( &self, half_depth: f32, isometry: impl Into<Isometry3d>, ) -> Aabb3d

Get an axis-aligned bounding box for an extrusion with this shape as a base and the given half_depth, transformed by the given translation and rotation.

fn extrusion_bounding_sphere( &self, half_depth: f32, isometry: impl Into<Isometry3d>, ) -> BoundingSphere

Get a bounding sphere for an extrusion of the base_shape with the given half_depth with the given translation and rotation

impl<P> Clone for Ring<P>

where P: Clone + Primitive2d,

fn clone(&self) -> Ring<P>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<P> Debug for Ring<P>

where P: Debug + Primitive2d,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<P> Measured2d for Ring<P>

where P: Primitive2d + Measured2d,

fn area(&self) -> f32

Get the area of the shape

fn perimeter(&self) -> f32

Get the perimeter of the shape

impl<P> PartialEq for Ring<P>

where P: PartialEq + Primitive2d,

fn eq(&self, other: &Ring<P>) -> 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.

impl<P> Copy for Ring<P>

where P: Copy + Primitive2d,

impl<T> Primitive2d for Ring<T>

where T: Primitive2d,

impl<P> StructuralPartialEq for Ring<P>

where P: Primitive2d,
