Macro rs_graph::nodevec
[−]
[src]
macro_rules! nodevec { ( $ g : expr ; $ elem : expr ) => { ... }; ( $ g : expr , $ vec : expr ) => { ... }; }
Create a node vector associated with a graph.
Example
Create a vector with all elements set to some value, use nodevec![g; x]
let g = peterson::<LinkedListGraph>(); let weights = nodevec![&g; 0]; assert!(g.nodes().all(|u| weights[u] == 0));
Convert an existing vector to a NodeVec
, use nodevec![g, v]
.
Note that the size of v
must be exactly g.num_nodes()
.
let g = peterson::<LinkedListGraph>(); let weights: Vec<_> = (0..g.num_nodes()).collect(); let weights = nodevec![&g, weights]; assert!(g.nodes().all(|u| weights[u] == g.node_id(u)));
