pub struct NoExpand<'s>(pub &'s [u8]);
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::bytes::{NoExpand, Regex};
let re = Regex::new(r"(?<last>[^,\s]+),\s+(\S+)").unwrap();
let result = re.replace(b"Springsteen, Bruce", NoExpand(b"$2 $last"));
assert_eq!(result, &b"$2 $last"[..]);
