Enum Interference

#[non_exhaustive]
pub enum Interference {
    Clear,
    Touching,
    Penetrating,
}

What two meshes do to each other.

Deliberately three states, not a boolean. A model checker that cannot distinguish “touching” from “overlapping” either floods the report with every abutting wall or silently drops real interferences.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Clear

No triangle pair meets, within the separation tested.

Touching

Triangles meet only at shared vertices, edges, or coplanar contact. Two slabs sharing a face are in contact, not in conflict.

Penetrating

At least one pair crosses transversally: the solids share volume.

Trait Implementations

impl Clone for Interference

fn clone(&self) -> Interference

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Interference

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

Formats the value using the given formatter.

impl PartialEq for Interference

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