Enum WeightConfig 

pub enum WeightConfig {
    Property {
        name: String,
        default_weight: f64,
    },
    Constant(f64),
}

Weight extraction configuration.

Defines how edge weights are extracted from edge properties.

Variants

Property

Use a specific property name as the weight. Falls back to default_weight if the property is not found.

Fields

name: String

The name of the property to use as weight.

default_weight: f64

The default weight if the property is not found.

Constant(f64)

Use a constant weight for all edges.

Implementations

impl WeightConfig

pub fn property(name: impl Into<String>) -> Self

Create a weight config that uses a specific property.

pub fn property_with_default(name: impl Into<String>, default: f64) -> Self

Create a weight config that uses a specific property with a default value.

pub const fn constant(weight: f64) -> Self

Create a weight config that uses a constant weight.

pub fn extract_weight(&self, edge: &Edge) -> GraphResult<f64>

Extract the weight from an edge based on this configuration.

Returns

• Ok(weight) - The extracted weight
• Err - If the weight value is invalid (non-numeric)
