Struct WangId 

pub struct WangId {
    pub colors: [u8; 8],
}

Wang ID using array storage (Tiled-compatible) Color 0 = empty/no terrain Layout: [Top, TopRight, Right, BottomRight, Bottom, BottomLeft, Left, TopLeft]

Fields

colors: [u8; 8]

Implementations

impl WangId

pub const WILDCARD: WangId

Wildcard WangId (all zeros = matches anything)

pub fn filled(terrain: u8) -> WangId

Create a WangId with all positions set to one terrain

pub fn color_at(&self, pos: WangPosition) -> u8

Get color at position (0 = empty)

pub fn set_color(&mut self, pos: WangPosition, color: u8)

Set color at position

pub fn color_at_index(&self, i: usize) -> u8

Get color at index (0 = empty)

pub fn set_color_at_index(&mut self, i: usize, color: u8)

Set color at index

pub fn opposite_index(i: usize) -> usize

Get opposite index (position on neighbor that faces us)

pub fn is_corner(i: usize) -> bool

Check if index is a corner (odd indices: 1,3,5,7)

pub fn next_index(i: usize) -> usize

Get next index clockwise

pub fn prev_index(i: usize) -> usize

Get previous index counter-clockwise

pub fn has_any_terrain(&self) -> bool

Check if this WangId has any terrain set

Trait Implementations

impl Clone for WangId

fn clone(&self) -> WangId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WangId

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

Formats the value using the given formatter.

impl Default for WangId

fn default() -> WangId

Returns the “default value” for a type.

impl Hash for WangId

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

where __H: Hasher,

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 WangId

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