solverforge-maps 2.1.x: Matrix Route Distances

solverforge-maps 2.1.x is the current maps line for routing and delivery applications. The latest patch, 2.1.4, is available on crates.io, documented on docs.rs, and tagged in the source repository.

Patch releases are folded into this line note instead of published as separate release-note pages.

What Changed

TravelTimeMatrix now stores route distances alongside travel times:

• matrix.get(from, to) returns travel time in seconds
• matrix.distance_meters(from, to) returns meters along the same fastest-time path
• matrix.row(from) returns a full row of travel times
• matrix.row_distances(from) returns the matching row of route distances
• matrix.as_slice() exposes the flat travel-time data
• matrix.distances_as_slice() exposes the flat distance data

The distance matrix preserves the same semantics as the travel-time matrix: diagonal pairs are zero, unreachable pairs use UNREACHABLE, and out-of-bounds access returns None.

Upgrade

Use the crates.io package pin:

[dependencies]
solverforge-maps = "2.1.4"

Example

let matrix = network.compute_matrix(&locations, None).await;

let time_seconds = matrix.get(0, 1);
let distance_meters = matrix.distance_meters(0, 1);
let all_times_from_depot = matrix.row(0);
let all_distances_from_depot = matrix.row_distances(0);

Use the new distance accessors for reporting, diagnostics, mileage displays, and secondary route-cost views that need to stay aligned with the fastest-time matrix used by the solver.
