Struct Sides 

pub struct Sides {
    pub first: i8,
    pub second: i8,
}

Which side of each support the ball rolls on.

A rolling ball sits at P + s·r·n for one sign s per support: outward for a convex seat, inward for a concave one, and one of each where the blend runs along a step. The pair is not guessed from the normals ( normals cannot tell a step from a slot) but tried, and the combination that gives a ball genuinely touching both is the seat.

Fields

first: i8

The sign on the first support’s normal.

second: i8

The sign on the second’s.

Trait Implementations

impl Clone for Sides

fn clone(&self) -> Sides

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Sides

impl Debug for Sides

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

Formats the value using the given formatter.

impl Eq for Sides

impl PartialEq for Sides

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