Crate tree_graphviz 

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. 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.

Traits

TreeVizNode

A trait that represents a node in an arbitrary tree structure. To use this with draw_nodes, you also need to implement std::hash::Hash.

Functions

draw_nodes

Returns a visualisation of the tree with the root node node in the GraphViz DOT format, as a string.
