Struct NoExpand
pub struct NoExpand<'s>(pub &'s str);
Expand description
A helper type for forcing literal string replacement.
It can be used with routines like Regex::replace
and
Regex::replace_all
to do a literal string replacement without expanding
$name
to their corresponding capture groups. This can be both convenient
(to avoid escaping $
, for example) and faster (since capture groups
don’t need to be found).
's
is the lifetime of the literal string to use.
§Example
use regex::{NoExpand, Regex};
let re = Regex::new(r"(?<last>[^,\s]+),\s+(\S+)").unwrap();
let result = re.replace("Springsteen, Bruce", NoExpand("$2 $last"));
assert_eq!(result, "$2 $last");
