A simple crate for generating GraphViz dot directed trees,
based on an arbitrary tree structure.
A tree can be any struct that implements:
- `std::string::ToString`
- `std::hash::Hash`
- and `TreeVizNode`
Currently, this crate does not support recursive elements within a tree.
This crate aims to be dependency free, and fast.
An optional `"async"` feature is available and provides an async variant of
`draw_nodes` - `draw_nodes_async`, which will recurse through a
node's children concurrently.
This introduces a dependency on the `futures` crate, but may be quicker, especially if
futures is already in your dependency tree.
If you want to run tests on this crate, use `cargo test --all-features`,
or the async-related tests will not run.
