GraphML output support for [petgraph]

This crate extends petgraph with GraphML output support.

This crate exports a single type [GraphMl] which combines a build-pattern for configuration and provides creating strings ([GraphMl::to_string]) and writing to writers ([GraphMl::to_writer]).

Usage

Add this to your Cargo.toml:

toml [dependencies] petgraph-graphml = "1.0.0"

Example

For a simple graph like this is the generated GraphML output.

```rust let graph = makegraph(); // Configure output settings // Enable pretty printing and exporting of node weights. // Use the Display implementation of NodeWeights for exporting them. let graphml = GraphMl::new(&graph) .prettyprint(true) .exportnodeweights_display();

asserteq!( graphml.tostring(), r#" 0 1 2 "#, ); ```
