Fields

graph_name: String

src: u64

dst: u64

Single destination. Used when targets is empty.

targets: Vec<u64>

Optional destination set; the search stops once the k cheapest of these are settled. When non-empty, dst is ignored.

edge_type: String

optional: only traverse this edge type

weight_encoding: i32

weight_key: String

key for TEXT_KEY / JSON_KEY (default “weight”)

default_weight: f64

fallback cost when no weight decodes (default 1.0)

algorithm: i32

k: u32

k-shortest loopless paths via Yen’s algorithm (0 or 1 = single best path).

as_of: u64

As-of timestamp (ms): only edges live at this instant are traversed (valid_from <= as_of < valid_to, valid_to == 0 meaning no expiry). 0 = no temporal filter.

max_cost: f64

Prune any path whose accumulated cost exceeds this (0 = no limit).

max_expansions: u64

Safety bound on settled nodes per Dijkstra run (0 = engine default).

tx_as_of: u64

As-of-then transaction-time filter (ms): only traverse edges believed at this recorded-time (tx_from <= tx_as_of && (tx_to == 0 || tx_to > tx_as_of)). 0 = no transaction-time filter.
