Module graphviz_rust::cmd
source · Expand description
It allows to execute cmd engine passing extra parameters
It is important: to execute it properly it needs to have an executable package on the system
The extra information can be found in layouts and outputs
Example:
use dot_structures::*;
use dot_generator::*;
use graphviz_rust::attributes::*;
use graphviz_rust::cmd::{CommandArg, Format};
use graphviz_rust::exec;
use graphviz_rust::printer::{PrinterContext,DotPrinter};
fn graph_to_output(){
let mut g = graph!(id!("id");
node!("nod"),
subgraph!("sb";
edge!(node_id!("a") => subgraph!(;
node!("n";
NodeAttributes::color(color_name::black), NodeAttributes::shape(shape::egg))
))
),
edge!(node_id!("a1") => node_id!(esc "a2"))
);
let graph_svg = exec(g, &mut PrinterContext::default(), vec![
CommandArg::Format(Format::Svg),
]).unwrap();
}
fn graph_to_file(){
let mut g = graph!(id!("id"));
let mut ctx = PrinterContext::default();
ctx.always_inline();
let empty = exec(g.print(&mut ctx), vec![
CommandArg::Format(Format::Svg),
CommandArg::Output("1.svg".to_string())
]);
}
