Trait NodeRef

pub trait NodeRef: Copy {
    type NodeId;
    type Weight;

    // Required methods
    fn id(&self) -> Self::NodeId;
    fn weight(&self) -> &Self::Weight;
}

A node reference.

Required Associated Types

type NodeId

type Weight

Required Methods

fn id(&self) -> Self::NodeId

fn weight(&self) -> &Self::Weight

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<'a, Id, W> NodeRef for (Id, &'a W)

impl<Id> NodeRef for (Id, ())

where Id: Copy,

type NodeId = Id

type Weight = ()

fn id(&self) -> Self::NodeId
