sodg 0.0.3

This Rust library helps you build a Simple Object DiGraph (SODG) for reo compiler of EO programs.

Create a graph:

use sodg::Sodg;
let mut g = Sodg::empty();
g.add(0)?; // add a vertex no.0
g.add(1)?; // add a vertex no.1
g.bind(0, 1, "foo")?; // connect v0 to v1 with label "foo"
g.put(1, "Hello, world!".as_bytes().to_vec())?; // attach data to v1

You can find a vertex by the label of an edge departing from another vertex:

let id = g.kid(0, "foo")?; // returns 1

You can find all kids of a vertex:

let kids: Vec<(String, u32)> = g.kids(0);

You can read the data of a vertex:

let bytes: Vec<u8> = g.data(1)?; // empty if no data written before

Then, you can print the graph:

println!("{:?}", g);

Also, you can serialize and deserialize the graph.
