Struct PackedCoord 

pub struct PackedCoord(/* private fields */);

Bit-packed coordinate representation for memory efficiency

Layout (64 bits): [63:44] Reserved (20 bits) - MUST BE ZERO [43:24] Row (20 bits) - 0 to 1,048,575 (zero-based) [23:10] Col (14 bits) - 0 to 16,383 (zero-based) [9:0] Reserved (10 bits) - MUST BE ZERO

Implementations

impl PackedCoord

pub const INVALID: Self

pub const RESERVED_MASK: u64 = 18_446_726_481_523_508_223u64

pub fn new(row: u32, col: u32) -> Self

Creates a new PackedCoord from row and column indices

Safety Invariants

• Row must be <= 1,048,575 (20 bits)
• Column must be <= 16,383 (14 bits)
• Reserved bits [63:44] and [9:0] MUST remain zero

pub fn row(self) -> u32

pub fn col(self) -> u32

pub fn as_u64(self) -> u64

pub fn is_valid(self) -> bool

pub fn normalize(self) -> Self

Trait Implementations

impl Clone for PackedCoord

fn clone(&self) -> PackedCoord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackedCoord

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

Formats the value using the given formatter.

impl Hash for PackedCoord

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 PackedCoord

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