Enum LeidenObjective 

pub enum LeidenObjective {
    Modularity,
    Cpm,
    Er,
}

Quality function (objective) that Leiden optimises. Mirrors igraph_leiden_objective_t.

Variants

Modularity

Generalised modularity Q = 1/(2m) Σ_ij (A_ij − γ k_i k_j / (2m)) δ(c_i,c_j). Edge weights must not be negative.

Cpm

Constant Potts Model Q = 1/(2m) Σ_ij (A_ij − γ) δ(c_i,c_j). Edge weights are allowed to be negative.

Er

Erdős-Rényi Q = 1/(2m) Σ_ij (A_ij − γ·p) δ(c_i,c_j), with p the weighted density. Edge weights must not be negative.

Trait Implementations

impl Clone for LeidenObjective

fn clone(&self) -> LeidenObjective

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LeidenObjective

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

Formats the value using the given formatter.

impl PartialEq for LeidenObjective

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