Trait IncidenceWeight 

pub trait IncidenceWeight: IncidenceBase {
    type Weight: Copy;

    // Required method
    fn incidence_weight(&self, incidence: Self::IncidenceId) -> Self::Weight;
}

Optional total weight capability for topology incidences.

A view implements this trait only when every visible incidence has a weight representation. The topology layer does not interpret the value; algorithms define their own numeric contracts separately.

Performance

Lookup should be O(1) unless an implementation documents a weaker contract.

Required Associated Types

type Weight: Copy

Copyable weight representation attached to each visible incidence.

Performance

Values should be O(1) to copy.

Required Methods

fn incidence_weight(&self, incidence: Self::IncidenceId) -> Self::Weight

Returns the weight attached to incidence.

Performance

Expected O(1) unless the implementation documents otherwise.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
