The text for a graphviz label on a node or edge.
Variants
LabelStr(Cow<'a, str>)
🔬 This is a nightly-only experimental API. (rustc_private
)

instead?
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 is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
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 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.

yields same content as self. The result obeys the law
render(lt
) == render(EscStr(lt.pre_escaped_content())
) for
