Macro enso_data::dependency_graph

macro_rules! dependency_graph {
    ($($fst:tt -> $snd:tt),* $(,)?) => { ... };
}

Utility macro allowing easy construction of the DependencyGraph. The following code:

use crate::enso_data::dependency_graph;
dependency_graph!(1->2, 2->3);

will produce:

{
    let mut graph = DependencyGraph::new();
    graph.insert_dependency(1,2);
    graph.insert_dependency(2,3);
    graph
}
