rustHow to escape a Rust regex?

To escape a Rust regex, you can use the \ character. This will tell the regex engine to treat the following character as a literal instead of a special character. For example, the following code will match the literal string \d+:

let re = Regex::new(r"\\d+").unwrap();

The code consists of the following parts:

• Regex::new: This is a function from the regex crate that creates a new Regex object.
• r"\\d+": This is a raw string literal that contains the regex pattern. The \ character is escaped with another \ character, so that it is treated as a literal instead of a special character.
• unwrap: This is a method that is called on the Regex object to get the underlying Regex value.
