Struct PageRankConfig 

pub struct PageRankConfig {
    pub damping: f64,
    pub max_iters: u32,
    pub tol: f64,
    pub edge_type: Option<String>,
    pub direction: AlgoDir,
    pub budget_ms: u64,
}

Configuration for [GraphDb::pagerank].

Fields

damping: f64

Damping factor (probability of following an edge, not teleporting). Default 0.85.

max_iters: u32

Maximum number of power-iteration steps. Default 50.

tol: f64

Convergence tolerance (L1 norm over all nodes). Default 1e-6.

edge_type: Option<String>

Restrict edges to this type. None uses all edge types (unified topology).

direction: AlgoDir

Edge direction to follow. Dir::Out follows out-edges (standard web PageRank); Dir::In follows in-edges (authority scores); Dir::Both treats all edges as undirected.

budget_ms: u64

Wall-clock budget (milliseconds) for the HTTP server endpoint. 0 means no budget (run to convergence or max_iters).
