Struct PathWithMetrics 

Source 
pub struct PathWithMetrics {
    pub path: Vec<OffchainPublicKey>,
    pub cost: f64,
    pub total_latency_ms: Option<u32>,

}
Expand description

A candidate path paired with its accumulated traversal cost and per-path quality metrics.

The cost is a multiplicative product of per-edge quality scores in (0.0, 1.0] — higher means better quality.

Aggregate fields are Option<T> with per-field None semantics documented on each field. Latency-measured paths are preferred during pruning; paths with None latency fill remaining slots up to the anonymity floor.

Fields§

§path: Vec<OffchainPublicKey>

The path nodes (excluding source): [intermediates..., dest].

§cost: f64

Accumulated traversal cost.

§total_latency_ms: Option<u32>

Sum of per-edge EMA latencies in milliseconds. None if any edge along the path has no measured latency.

§min_probe_success_rate: Option<f64>

Worst per-edge probe success rate along the path, taken as the minimum of the available immediate (1-hop) and intermediate (multi-hop) probe rates per edge. None if no edge has any probe data.

§min_ack_rate: Option<f64>

Worst per-edge acknowledgment rate along the path. None if no edge has sent any messages yet.

§fundable_tickets_floor: Option<u128>

Smallest number of single-hop tickets any edge along the path can still fund.

Derived per query from each edge’s balance and the current ticket face value — never stored on an edge, which would stale the graph whenever the price moves. None if no edge carries balance data.
