Struct HashableFloat2D 

pub struct HashableFloat2D {
    pub x: f64,
    pub y: f64,
}

A wrapper type for f64 arrays that implements Hash and Eq This allows using f64 arrays as keys in HashMaps

Fields

x: f64

X coordinate

y: f64

Y coordinate

Implementations

impl HashableFloat2D

pub fn new(x: f64, y: f64) -> HashableFloat2D

Create a new HashableFloat2D from f64 coordinates

pub fn from_array(arr: [f64; 2]) -> HashableFloat2D

Convert from array representation

pub fn to_array(&self) -> [f64; 2]

Convert to array representation

pub fn distance(&self, other: &HashableFloat2D) -> f64

Calculate Euclidean distance to another point

Trait Implementations

impl Clone for HashableFloat2D

fn clone(&self) -> HashableFloat2D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HashableFloat2D

impl Debug for HashableFloat2D

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

Formats the value using the given formatter.

impl Eq for HashableFloat2D

impl Hash for HashableFloat2D

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 HashableFloat2D

fn eq(&self, other: &HashableFloat2D) -> 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.
