v0.13.0 Upgrade Guide

• Set your go.mod requirements to match the new version.

require (
   github.com/nextmv-io/code/engines v0.13.0
   github.com/nextmv-io/code/hop v0.13.0
)

The here client received some updates. The WithAsyncTimeOut and WithAsyncPollingInterval have been removed and replaced by a cancellation context that is applied to the matrix functions.

cli := here.NewClient("<API_KEY>", here.WithAsyncTimeout(300), here.WithAsyncPollingInterval(600))
matrix, err := cli.DistanceMatrix(points)

The location measure - which handles service times - now also takes a new parameter, durationGroups, to apply an additional service time every time a group of stops is approached.

m := measure.Location(measure, serviceTimes)

The route.Operators option for router now has 2 parameters. The second parameter lets the user either replace or append the ALNS operators.

router, err := route.NewRouter(
    i.Stops,
    i.Vehicles,
    route.Operators(operators),
)
    if err != nil {
        return nil, err
}

The VehicleSorter sets the vehicle sorting function that determines the order in which the solver tries to assign locations.

assigner := fleetEngine.CustomAssigner(
    input,
    selector,
    groupers,
    filters,
)
