Struct Path 

pub struct Path {
    pub nodes: Vec<String>,
    pub total_weight: f64,
    pub edge_types: Vec<String>,
}

A path through the graph

Fields

nodes: Vec<String>

Ordered list of node IDs from source to target

total_weight: f64

Total weight/cost of the path

edge_types: Vec<String>

Edge labels along the path (canonical lower-snake-case strings). Resolved against the graph’s crate::storage::engine::graph_store::LabelRegistry when the caller needs the original LabelId.

Implementations

impl Path

pub fn start(node: &str) -> Path

Create a path with a single node (start)

pub fn extend( &self, node: &str, edge_label: impl Into<String>, weight: f64, ) -> Path

Extend path with a new node + edge label.

pub fn len(&self) -> usize

Path length (number of edges)

pub fn is_empty(&self) -> bool

Check if path is empty

pub fn source(&self) -> Option<&str>

Get source node

pub fn target(&self) -> Option<&str>

Get target node
