Struct BettiNumbers 

pub struct BettiNumbers {
    pub b0: usize,
    pub b1: usize,
    pub b2: usize,
}

Betti numbers at a given scale

Fields

b0: usize

β_0: number of connected components

b1: usize

β_1: number of 1-cycles (loops)

b2: usize

β_2: number of 2-cycles (voids)

Implementations

impl BettiNumbers

pub fn new(b0: usize, b1: usize, b2: usize) -> Self

Create from values

pub fn total(&self) -> usize

Total number of features

pub fn euler_characteristic(&self) -> i64

Euler characteristic χ = β_0 - β_1 + β_2

Trait Implementations

impl Clone for BettiNumbers

fn clone(&self) -> BettiNumbers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BettiNumbers

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

Formats the value using the given formatter.

impl PartialEq for BettiNumbers

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