Enum TorusKind 

pub enum TorusKind {
    Ring,
    Horn,
    Spindle,
}

How a torus’s minor radius compares with its major radius.

The three cases are genuinely different surfaces, and an algorithm that assumes the first will produce nonsense on the others: a spindle torus self-intersects, and a horn torus is tangent to itself at the poles.

Variants

Ring

minor < major: a ring, with a hole.

Horn

minor == major: the hole closes to a single point at each pole.

Spindle

minor > major: the surface passes through itself.

Trait Implementations

impl Clone for TorusKind

fn clone(&self) -> TorusKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TorusKind

impl Debug for TorusKind

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

Formats the value using the given formatter.

impl Eq for TorusKind

impl PartialEq for TorusKind

fn eq(&self, other: &TorusKind) -> 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.
