Enum GridConnectivity 

pub enum GridConnectivity {
    FourWay,
    EightWay,
    Hex,
}

Grid connectivity type, determines graph-distance metric.

Variants

FourWay

4-connected (Square4): graph distance = Manhattan |dr| + |dc|.

EightWay

8-connected (Square8): graph distance = Chebyshev max(|dr|, |dc|).

Hex

6-connected hex (Hex2D, axial coords): graph distance = max(|dq|, |dr|, |dq+dr|).

Trait Implementations

impl Clone for GridConnectivity

fn clone(&self) -> GridConnectivity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GridConnectivity

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

Formats the value using the given formatter.

impl PartialEq for GridConnectivity

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