# Struct regex::bytes::NoExpand [−] [src]

    pub struct NoExpand<'r>(pub &'r [u8]);

NoExpand indicates literal byte string replacement.

It can be used with `replace` and `replace_all` to do a literal byte 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.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
