impl<NI, EV, U> DegreePartitionOp<NI, EV> for U
where NI: Idx, U: Graph<NI> + UndirectedDegrees<NI> + UndirectedNeighborsWithValues<NI, EV>,

Source§

fn degree_partition(&self, concurrency: usize) -> Vec<Range<NI>>

Creates a greedy range-based degree partition of the nodes.

It is greedy in the sense that it goes through the node set only once and simply adds a new range to the result whenever the current range’s nodes’ degrees sum up to at least the average node degree.

§Example
let graph: UndirectedCsrGraph<u32> = GraphBuilder::new()
    .edges(vec![(0, 1), (0, 2), (0, 3), (0, 3)])
    .build();

let partition: Vec<Range<u32>> = graph.degree_partition(2);

assert_eq!(partition.len(), 2);
assert_eq!(partition[0], 0..1);
assert_eq!(partition[1], 1..4);

where T: Send, F: Fn(&G, NI, &mut T) + Send + Sync,

For each node calls a given function with the node and its corresponding mutable state in parallel based on the provided node partition.

The parallelization is done by means of a rayon based fork join with a task for each range in the provided node partition.
