Struct PageRankOptions 

pub struct PageRankOptions {
    pub damping: f64,
    pub directed: bool,
    pub algo: PageRankAlgo,
}

Tuning parameters of the PageRank family of functions (pagerank, personalized_pagerank, personalized_pagerank_vs).

The Default is the classic setting: damping 0.85, directed paths, PageRankAlgo::Prpack.

use igraph::centrality::{PageRankAlgo, PageRankOptions};

let opts = PageRankOptions::default().with_damping(0.5).with_algo(PageRankAlgo::Arpack);
assert_eq!((opts.damping, opts.directed, opts.algo), (0.5, true, PageRankAlgo::Arpack));

Fields

damping: f64

The damping factor (d in the original paper): the probability that the random walker follows an edge instead of restarting. Must be in [0, 1].

directed: bool

Whether to follow edge directions in directed graphs (ignored for undirected graphs).

algo: PageRankAlgo

The implementation to use.

Implementations

impl PageRankOptions

pub fn with_damping(self, damping: f64) -> Self

Sets the damping factor.

pub fn with_directed(self, directed: bool) -> Self

Sets whether edge directions are followed (directed).

pub fn with_algo(self, algo: PageRankAlgo) -> Self

Sets the implementation (algo).

Trait Implementations

impl Clone for PageRankOptions

fn clone(&self) -> PageRankOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PageRankOptions

impl Debug for PageRankOptions

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

Formats the value using the given formatter.

impl Default for PageRankOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for PageRankOptions

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