Trait EdgeRef 

pub trait EdgeRef {
    type NodeIndex;

    // Required methods
    fn get_edge(
        &self,
        index: usize,
    ) -> Option<(&Self::NodeIndex, &Self::NodeIndex)>;
    fn capacity(&self) -> usize;

    // Provided method
    fn valid_edge(&self, index: usize) -> bool { ... }
}

Reference to an edge, represented as a pair of node indices

This trait provides basic access to edge data in edge collections. It’s used to implement iterators and provide a common interface for accessing edge information.

Required Associated Types

type NodeIndex

Required Methods

fn get_edge(&self, index: usize) -> Option<(&Self::NodeIndex, &Self::NodeIndex)>

Reference to an edge at given index

fn capacity(&self) -> usize

Total capacity of the container

Provided Methods

fn valid_edge(&self, index: usize) -> bool

Check if edge at index exists

Dyn Compatibility

This trait is dyn compatible.

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