Struct SqDist 

pub struct SqDist { /* private fields */ }

An exact squared distance: the rational num / den.

Implementations

impl SqDist

pub const ZERO: SqDist

Zero.

pub fn is_zero(&self) -> bool

true when the distance is zero.

pub fn to_f64(&self) -> f64

The squared distance as f64 (correctly ordered up to rounding).

pub fn distance_f64(&self) -> f64

The distance as f64.

pub fn cmp_dist(&self, d: u64) -> Ordering

Exact comparison of this squared distance with d * d.

impl Eq for SqDist

impl Ord for SqDist

fn cmp(&self, o: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for SqDist

fn eq(&self, o: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SqDist

fn partial_cmp(&self, o: &Self) -> 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
