Struct Barcode 

pub struct Barcode {
    pub pairs: Vec<PersistencePair>,
    pub betti_curve: Vec<(f64, Vec<usize>)>,
}

The full persistence barcode for all dimensions.

Fields

pairs: Vec<PersistencePair>

betti_curve: Vec<(f64, Vec<usize>)>

Betti curve sampled at each unique filtration value: (epsilon, [β₀, β₁, β₂, …])

Implementations
