Struct PersistentInterval 

pub struct PersistentInterval {
    pub birth: f64,
    pub death: f64,
    pub dimension: usize,
}

A bar in a persistence diagram: [birth, death) for homology class H_k.

An essential class (never destroyed) has death == f64::INFINITY.

Fields

birth: f64

Filtration value at which this class was born.

death: f64

Filtration value at which this class died; INFINITY if essential.

dimension: usize

Homological dimension (0 = connected component, 1 = loop, …).

Implementations

impl PersistentInterval

pub fn persistence(&self) -> f64

Persistence (lifetime) of this interval. Returns INFINITY for essential classes.

pub fn is_essential(&self) -> bool

Returns true if this class is essential (never destroyed).

Trait Implementations

impl Clone for PersistentInterval

fn clone(&self) -> PersistentInterval

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PersistentInterval

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

Formats the value using the given formatter.

impl PartialEq for PersistentInterval

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