This trait defines multi-trip strategy.

Required methods

fn is_reload_job(&self, job: &Job) -> bool

Returns true if job is reload.

fn is_reload_single(&self, single: &Single) -> bool

Returns true if single job is reload.

fn is_assignable(&self, route: &Route, job: &Job) -> bool

Returns true if given job is reload and can be used with given route.

fn is_reload_needed(&self, current: &T, max_capacity: &T) -> bool

Returns true when current capacity is close max_capacity.

fn has_reloads(&self, route_ctx: &RouteContext) -> bool

Returns true if route context has reloads.

fn get_reload<'a>(&self, activity: &'a Activity) -> Option<&'a Arc<Single>>

Returns reload job from activity or None.

fn get_reloads<'a>(
    &'a self,
    route: &'a Route,
    jobs: &'a [Job]
) -> Box<dyn Iterator<Item = Job> + Send + Sync + 'a>

Gets all reloads for specific route from jobs collection.
