Fields

required: Vec<Job>

List of jobs which require permanent assignment.

ignored: Vec<Job>

unassigned: HashMap<Job, UnassignmentInfo>

Map of jobs which cannot be assigned and within reason code.

locked: HashSet<Job>

Specifies jobs which should not be affected by ruin.

routes: Vec<RouteContext>

Set of routes within their state.

registry: RegistryContext

Keeps track of used routes and resources.

state: HashMap<StateKey, StateValue>

A collection of data associated with solution.

Implementations

impl SolutionContext

pub fn get_jobs_amount(&self) -> usize

Returns amount of jobs considered by solution context. NOTE: the amount can be different for partially solved problem from original problem.

pub fn keep_routes(&mut self, predicate: &dyn Fn(&RouteContext) -> bool)

Keep routes for which given predicate returns true.

pub fn deep_copy(&self) -> Self

Creates a deep copy of SolutionContext.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
