Struct EdgeWeight 

pub struct EdgeWeight {
    pub distance: f64,
    pub time: f64,
    pub monetary: f64,
    pub custom: HashMap<String, f64>,
}

Multi-criteria edge weight supporting distance, time, and custom costs

Fields

distance: f64

Distance cost (e.g., meters)

time: f64

Time cost (e.g., seconds)

monetary: f64

Monetary cost (e.g., toll fees)

custom: HashMap<String, f64>

Custom weight dimensions (named)

Implementations

impl EdgeWeight

pub fn from_distance(distance: f64) -> Self

Create a simple weight with only distance

pub fn from_distance_time(distance: f64, time: f64) -> Self

Create a weight with distance and time

pub fn new(distance: f64, time: f64, monetary: f64) -> Self

Create a weight with all three primary dimensions

pub fn with_custom(self, name: String, value: f64) -> Self

Add a custom weight dimension

pub fn weighted_cost(&self, criteria: &HashMap<String, f64>) -> f64

Compute a weighted combination of all costs

criteria maps weight names to their multiplier coefficients. Built-in names: “distance”, “time”, “monetary”.

pub fn primary(&self) -> f64

Get the primary weight (distance by default)

Trait Implementations

impl Clone for EdgeWeight

fn clone(&self) -> EdgeWeight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeWeight

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

Formats the value using the given formatter.

impl Default for EdgeWeight

fn default() -> Self

Returns the “default value” for a type.
