Struct dot_writer::EdgeList

pub struct EdgeList<'d, 'w> { /* fields omitted */ }

An EdgeList is returned from Scope::edge and can be used to set the attributes of an edge, or to chain additional nodes onto the edge statement.

Implementations

impl<'d, 'w> EdgeList<'d, 'w>

pub fn edge<N: AsRef<[u8]>>(&mut self, node_id: N) -> &mut Self

Adds another edge from the last node added to node_id. Note that nodes do not need to be already defined by Scope::node_auto or by Scope::node_named (unless you want to set node-specifc attributes).

use dot_writer::DotWriter;

let mut output_bytes = Vec::new();
{
  let mut writer = DotWriter::from(&mut output_bytes);
  writer.set_pretty_print(false);
  writer.digraph().edge("a", "b").edge("c").edge("d");
}
assert_eq!(
    std::str::from_utf8(&output_bytes).unwrap(),
    "digraph {a->b->c->d;}"
);

pub fn attributes(self) -> AttributesList<'d, 'w>

Start writing the attributes section of an edge definition. See the returned structure for what attributes can be set. Note that no more nodes can be added after this function is called.
