Crate gml_parser

This crate allows for reading Graph Modeling Language (GML) files.

This crate first parses the GML into GMLObjects and GMLValues. Then the root GMLObject can be transformed into a Graph containing Nodes and Edges.

Examples

use gml_parser::{GMLObject, Graph};

let data = r#"
graph [            
   id 4           
   node [         
       id 0       
   ]              
   node [         
       id 1       
   ]              
   edge [         
       source 1   
       target 0   
       label "Edge"
   ]              
]"#;
let root = GMLObject::from_str(data).unwrap();
let graph = Graph::from_gml(root).unwrap();
assert_eq!(graph.id, Some(4));
assert_eq!(graph.nodes.len(), 2);
assert_eq!(graph.edges.len(), 1);

Limitations

• This implementation can be fragile and GML is not a very picky standard
• We duplicate the data when parsing which can have performance impacts on very large graphs
