Struct MortonCode 

pub struct MortonCode(pub u64);

A 64-bit Morton (Z-order) code.

Wraps a raw u64. The encoder masks off bit 63 to preserve the NDS semantics of the reference implementation.

Tuple Fields

0: u64

Implementations

impl MortonCode

pub fn new(morton_code: u64) -> Self

Construct a MortonCode from a raw 64-bit value.

Most callers use MortonCode::from_nds_coordinates instead.

pub fn from_nds_coordinates(x: i32, y: i32) -> MortonCode

Encode NDS integer coordinates into a Morton (Z-order) code.

x is NDS longitude (signed 32-bit), y is NDS latitude (signed 31-bit). Out-of-range inputs are wrapped, exactly as in the Python reference. Bit 63 is masked off.

pub fn to_nds_coordinates(&self) -> (i32, i32)

Decode this Morton code back into NDS integer coordinates.

Inverse of MortonCode::from_nds_coordinates. Returns (x, y) as signed integers: NDS longitude (32-bit) and NDS latitude (31-bit).

pub fn value(&self) -> u64

Get the raw Morton code value (matches the C++/Python value() API).

Trait Implementations

impl Clone for MortonCode

fn clone(&self) -> MortonCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MortonCode

impl Debug for MortonCode

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

Formats the value using the given formatter.

impl Display for MortonCode

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

Formats the value using the given formatter.

impl Eq for MortonCode

impl Hash for MortonCode

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 Ord for MortonCode

fn cmp(&self, other: &MortonCode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MortonCode

fn eq(&self, other: &MortonCode) -> 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 PartialOrd for MortonCode

fn partial_cmp(&self, other: &MortonCode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
