}
🔬 This is a nightly-only experimental API. (rustc_private)

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

Variants

🔬 This is a nightly-only experimental API. (rustc_private)

This kind of label preserves the text directly as is.

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

🔬 This is a nightly-only experimental API. (rustc_private)

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.

🔬 This is a nightly-only experimental API. (rustc_private)

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