Struct rustc_ap_rustc_graphviz::Id [−][src]
pub struct Id<'a> { /* fields omitted */ }
Expand description
Id
is a Graphviz ID
.
Implementations
Creates an Id
named name
.
The caller must ensure that the input conforms to an
identifier format: it must be a non-empty string made up of
alphanumeric or underscore characters, not beginning with a
digit (i.e., the regular expression [a-zA-Z_][a-zA-Z_0-9]*
).
(Note: this format is a strict subset of the ID
format
defined by the DOT language. This function may change in the
future to accept a broader subset, or the entirety, of DOT’s
ID
format.)
Passing an invalid string (containing spaces, brackets,
quotes, …) will return an empty Err
value.
