clippy 0.0.212 (265318d 2019-05-17)
I get the following error when linting code, and I have a feeling it might be a bug. If it is not, it maybe clippy can give a correct suggestion?
error: regex syntax error: unrecognized escape sequence --> src/compiler/utilities.rs:187:52 | 187 | static ref RE: Regex = Regex::new("^..?($|[\\/])").unwrap(); | ^^ | = note: #[deny(clippy::invalid_regex)] on by default = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#invalid_regex

I found the solution here. The reason it fails is because it should be escaped once for the string literal, and once for the regex. If possible, a better description of the problem would be nice.
