Struct regex::NoExpand

pub struct NoExpand<'t>(pub &'t str);

NoExpand indicates literal string replacement.

It can be used with replace and 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 performant (since capture groups don’t need to be found).

't is the lifetime of the literal text.
