Enum Orientation 

pub enum Orientation {
    Forward,
    Reversed,
    Internal,
    External,
}

Which side of a boundary the material is on.

docs/DATA_MODEL.md §3.

Variants

Forward

The material is on the surface’s default side.

Reversed

The material is on the other side.

Internal

The boundary lies inside the material: a stiffener edge embedded in a face, an edge that does not separate anything.

External

The boundary lies outside the material: reference geometry, carried along but bounding nothing.

Implementations

impl Orientation

pub const fn compose(self, inner: Self) -> Self

Compose an outer orientation with an inner one.

Applied at every level of descent: an edge’s orientation within a face depends on that face’s orientation within its shell, and so on to the root. Reversing a solid must therefore not touch a single child.

Internal and External absorb: a boundary that lies inside the material stays inside it however the shape around it is turned.

pub const fn reversed(self) -> Self

This orientation reversed.

Internal and External are unaffected; neither names a side, so neither has one to swap.

pub const fn is_boundary(self) -> bool

Whether this orientation names a side of the material at all.

Trait Implementations

impl Clone for Orientation

fn clone(&self) -> Orientation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Orientation

impl Debug for Orientation

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

Formats the value using the given formatter.

impl Default for Orientation

fn default() -> Orientation

Returns the “default value” for a type.

impl Eq for Orientation

impl Hash for Orientation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Orientation

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