This Rust library helps you build an object tree for reo compiler of EO programs.

Create a tree:

rust use sot::Sot; let mut sot = Sot::empty(); sot.add(0)?; // add a vertex no.0 sot.add(1)?; // add a vertex no.1 sot.bind(0, 1, "foo")?; // connect v0 to v1 with label "foo" sot.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:

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

You can find all kids of a vertex:

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

You can read the data of a vertex:

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

Then, you can print the tree:

rust println!("{:?}", sot);

Also, you can serialize and deserialize the tree.
