Graph search

graphsearch is a simple graph library for the rust programming language. graphsearch can be used for basic representation and manipulation of graph structures. At the moment featureset is quite limited.

Organization

• README.md - The document you are currently reading.
• Cargo.toml - The cargo definition for this package.
• src/lib.rs - The actual implementation of this library.

Features

• Graphs with vertex costs
• Breadth first search
• Depth first search
• Dijkstra's algorithm

Usage example

Here's a short basic example of using this library as an external crate:

extern crate graphsearch;
use graphsearch::{Graph, Node, Vertex};
fn main() {
  let testgraph = vec![Node{content: "Helsinki",
                            adjacent: vec![Vertex{cost: 20, node: 1},
                                           Vertex{cost: 50, node: 2}]},
                       Node{content: "Turku",
                            adjacent: vec![Vertex{cost: 30, node:2}]},
                       Node{content: "Tampere",
                            adjacent: Vec::new()}];
  let start: usize = 0;
  let target = "Tampere";
  let g = Graph::new(testgraph);
  let res = g.search(start, target); // uses dijkstras algorithm
  match res {
    None => {
      println!("Search returned None");
    }
    Some(result) => {
      println!("Search returned a path: {:?}", result);
      println!("The returned path cost: {}", g.cost_of_path(&result));
    }
  }
}
