Trait NodeKeyRef 

pub trait NodeKeyRef<'a, N, K>
where
    N: 'a,
    K: 'a,
{
    // Required methods
    fn node(&self) -> &'a N;
    fn key(&self) -> &'a K;
}

Trait representing (node, key) pairs stored on priority queues.

Required Methods

fn node(&self) -> &'a N

Returns a reference to the node.

fn key(&self) -> &'a K

Returns a reference to the key/priority of the node.

Dyn Compatibility

This trait is dyn compatible.

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