Struct vrp_core::construction::heuristics::RouteContext

pub struct RouteContext {
    pub route: Arc<Route>,
    pub state: Arc<RouteState>,
    // some fields omitted
}

Specifies insertion context for route.

Fields

route: Arc<Route>

Used route.

state: Arc<RouteState>

Insertion state.

Implementations

impl RouteContext

pub fn new(actor: Arc<Actor>) -> Self

Creates a new instance of RouteContext.

pub fn new_with_state(route: Arc<Route>, state: Arc<RouteState>) -> Self

Creates a new instance of RouteContext with arguments provided.

pub fn deep_copy(&self) -> Self

Creates a deep copy of RouteContext.

pub fn get_route_cost(&self) -> Cost

Gets route cost.

pub fn as_mut(&mut self) -> (&mut Route, &mut RouteState)

Unwraps given RouteContext as pair of mutable references. Marks context as stale.

pub fn route_mut(&mut self) -> &mut Route

Returns mutable reference to used Route. Marks context as stale.

pub fn state_mut(&mut self) -> &mut RouteState

Returns mutable reference to used RouteState. Marks context as stale.

pub fn is_stale(&self) -> bool

Returns true if context is stale. Context is marked stale when it is accessed by mut methods. A general motivation of the flag is to avoid recalculating non-changed states.

Trait Implementations

impl Clone for RouteContext

fn clone(&self) -> RouteContext

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for RouteContext

impl PartialEq<RouteContext> for RouteContext

fn eq(&self, other: &RouteContext) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
