Struct TreeCoord 

pub struct TreeCoord {
    pub x: i32,
    pub y: i32,
}

Identifies a lot in the infinite procedural tree. The pair (x, y) is the stable id of a node — saves store only owned lot coords, and the generator regenerates every other property from (TREE_SEED, x, y).

Origin (0, 0) is the player’s starting lot — the Index Finger homeland.

Fields

x: i32

y: i32

Implementations

impl TreeCoord

pub const ORIGIN: TreeCoord

pub const fn new(x: i32, y: i32) -> Self

pub fn manhattan(self) -> u32

Manhattan distance from origin, saturating so (i32::MIN, i32::MIN) returns u32::MAX instead of overflowing the sum (each unsigned_abs is up to 2^31; the plain sum overflows at i32::MIN + i32::MIN, panicking in debug builds).

Trait Implementations

impl Clone for TreeCoord

fn clone(&self) -> TreeCoord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TreeCoord

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

Formats the value using the given formatter.

impl Default for TreeCoord

fn default() -> TreeCoord

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TreeCoord

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TreeCoord

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 TreeCoord

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

impl Serialize for TreeCoord

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TreeCoord

impl Eq for TreeCoord
