pub struct Id<'a> { /* private fields */ }
Expand description

Id is a Graphviz ID.

Implementations§

source§

impl<'a> Id<'a>

source

pub fn new<Name: Into<Cow<'a, str>>>(name: Name) -> Result<Id<'a>, ()>

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.
