Function petgraph::algo::toposort [−] [src]

pub fn toposort<N, E, Ix>(g: &Graph<N, E, Directed, Ix>) -> Vec<NodeIndex<Ix>> where Ix: IndexType

Perform a topological sort of a directed graph.

Return a vector of nodes in topological order: each node is ordered before its successors.

If the returned vec contains less than all the nodes of the graph, then the graph was cyclic.

Search Tricks

Prefix searches with a type followed by a colon (e.g. fn:) to restrict the search to a given type.

Accepted types are: fn, mod, struct, enum, trait, type, macro, and const.

Search functions by type signature (e.g. vec -> usize or * -> vec)
