Struct BirthDeathPair 

pub struct BirthDeathPair {
    pub dimension: usize,
    pub birth: f64,
    pub death: Option<f64>,
}

Birth-death pair in persistence diagram

Fields

dimension: usize

Dimension of the feature (0 = component, 1 = loop, …)

birth: f64

Birth time

death: Option<f64>

Death time (None = essential, lives forever)

Implementations

impl BirthDeathPair

pub fn finite(dimension: usize, birth: f64, death: f64) -> Self

Create finite interval

pub fn essential(dimension: usize, birth: f64) -> Self

Create essential (infinite) interval

pub fn persistence(&self) -> f64

Persistence (lifetime) of feature

pub fn is_essential(&self) -> bool

Is this an essential feature (never dies)?

pub fn midpoint(&self) -> f64

Midpoint of interval

Trait Implementations

impl Clone for BirthDeathPair

fn clone(&self) -> BirthDeathPair

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BirthDeathPair

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

Formats the value using the given formatter.

impl PartialEq for BirthDeathPair

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