[][src]Enum rustc_ap_rustc_graphviz::LabelText

pub enum LabelText<'a> {
    LabelStr(Cow<'a, str>),
    EscStr(Cow<'a, str>),
    HtmlStr(Cow<'a, str>),
}

The text for a graphviz label on a node or edge.

Variants

LabelStr(Cow<'a, str>)

This kind of label preserves the text directly as is.

Occurrences of backslashes (\) are escaped, and thus appear as backslashes in the rendered label.

EscStr(Cow<'a, str>)

This kind of label uses the graphviz label escString type: http://www.graphviz.org/content/attrs#kescString

Occurrences of backslashes (\) are not escaped; instead they are interpreted as initiating an escString escape sequence.

Escape sequences of particular interest: in addition to \n to break a line (centering the line preceding the \n), there are also the escape sequences \l which left-justifies the preceding line and \r which right-justifies it.

HtmlStr(Cow<'a, str>)

This uses a graphviz HTML string label. The string is printed exactly as given, but between < and >. No escaping is performed.

Implementations

impl<'a> LabelText<'a>[src]

pub fn label<S: Into<Cow<'a, str>>>(s: S) -> LabelText<'a>[src]

pub fn escaped<S: Into<Cow<'a, str>>>(s: S) -> LabelText<'a>[src]

pub fn html<S: Into<Cow<'a, str>>>(s: S) -> LabelText<'a>[src]

pub fn to_dot_string(&self) -> String[src]

Renders text as string suitable for a label in a .dot file. This includes quotes or suitable delimiters.

pub fn prefix_line(self, prefix: LabelText<'_>) -> LabelText<'static>[src]

Puts prefix on a line above this label, with a blank line separator.

pub fn suffix_line(self, suffix: LabelText<'_>) -> LabelText<'static>[src]

Puts suffix on a line below this label, with a blank line separator.
