This crate is used to generate dot graphs with types defined in rust. The whole crate is implemented following the dot language specification listed at graphviz's website.
There is an optional feature attributes which implemented a subset of the attributes list of the dot language.
By enabling this feature, you will be able to write something like:
use tabbycat::attributes::*;
use tabbycat::AttrList;
let attrlist = AttrList::new()
.add_pair(fontsize(12.0))
.add_pair(label("test"))
.new_bracket()
.add_pair(fillcolor(Color::Blue))
.add_pair(arrowhead(ArrowShape::Orinv));
assert_eq!("[fontsize=12;label=\"test\";][fillcolor=blue;arrowhead=orinv;]", attrlist.to_string())use tabbycat::attributes::*;
use tabbycat::{AttrList, GraphBuilder, GraphType, Identity, StmtList, Edge, SubGraph};
let graph = GraphBuilder::default()
.graph_type(GraphType::DiGraph)
.strict(false)
.id(Identity::id("G").unwrap())
.stmts(StmtList::new()
.add_node(Identity::id("A").unwrap(), None, Some(AttrList::new().add_pair(color(Color::Red))))
.add_edge(Edge::head_node(Identity::id("B").unwrap(), None)
.arrow_to_node(Identity::id("C").unwrap(), None)
.add_attrpair(arrowhead(ArrowShape::Diamond)))
.add_subgraph(SubGraph::subgraph(Some(Identity::id("D").unwrap()),
StmtList::new()
.add_edge(Edge::head_node(Identity::id("E").unwrap(), None)
.arrow_to_node(Identity::id("F").unwrap(), None)))))
.build()
.unwrap();
println!("{}", graph);This will generate an output like:
digraph G{A[color=red;];B->C[arrowhead=diamond;];subgraph D{E->F;};}
