Struct LabelSubstContext 

pub struct LabelSubstContext<'a> {
    pub node_name: &'a str,
    pub graph_name: &'a str,
    pub tail_name: &'a str,
    pub head_name: &'a str,
    pub is_edge: bool,
    pub is_directed: bool,
    pub tail_port: Option<&'a str>,
    pub head_port: Option<&'a str>,
    pub label_text: &'a str,
    pub pen_color: Option<&'a str>,
    pub is_node: bool,
    pub has_label: bool,
}

Context for Graphviz object-based escape sequence substitution (\N, \G, \T, \H, \E, \L).

Fields

node_name: &'a str

graph_name: &'a str

tail_name: &'a str

head_name: &'a str

is_edge: bool

is_directed: bool

tail_port: Option<&'a str>

head_port: Option<&'a str>

label_text: &'a str

pen_color: Option<&'a str>

getPenColor(obj) (pencolor, else color), which an HTML label’s outermost table without a COLOR takes (make_html_label).

is_node: bool

The object is a node (its name may be empty).

has_label: bool

The object has a main label (ND_label, ED_label, GD_label), whose text is label_text even when empty; without one \L stays literal.
