Methods
impl<'a> Id<'a>
[src]
fn new<Name: IntoCow<'a, str>>(name: Name) -> Result<Id<'a>, ()>
Unstable (
rustc_private
)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.
