Enum EdgeBehavior 

pub enum EdgeBehavior {
    Clamp,
    Wrap,
    Absorb,
}

How a lattice space handles neighbors at its edges.

This is distinct from murk_core::BoundaryBehavior, which controls field value clamping. EdgeBehavior controls the topology — which cells are considered neighbors of boundary cells.

Examples

use murk_space::{Square4, EdgeBehavior, Space};

// Absorb: corner has 2 neighbors, interior has 4.
let absorb = Square4::new(4, 4, EdgeBehavior::Absorb).unwrap();
let corner: murk_core::Coord = vec![0i32, 0].into();
let interior: murk_core::Coord = vec![1i32, 1].into();
assert_eq!(absorb.neighbours(&corner).len(), 2);
assert_eq!(absorb.neighbours(&interior).len(), 4);

// Wrap: all cells have exactly 4 neighbors (torus).
let wrap = Square4::new(4, 4, EdgeBehavior::Wrap).unwrap();
assert_eq!(wrap.neighbours(&corner).len(), 4);

Variants

Clamp

Out-of-bounds neighbor maps to the boundary cell (self-loop).

Wrap

Out-of-bounds neighbor wraps to the opposite side (periodic).

Absorb

Out-of-bounds neighbor is omitted (fewer neighbors at edges).

Trait Implementations

impl Clone for EdgeBehavior

fn clone(&self) -> EdgeBehavior

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeBehavior

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

Formats the value using the given formatter.

impl Hash for EdgeBehavior

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 EdgeBehavior

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