rustHow to use modifiers in a Rust regex?

Modifiers are used to modify the behavior of a regular expression in Rust. They can be used to make a regex case-insensitive, to enable multi-line matching, and to enable Unicode support.

Example code

let re = Regex::new(r"(?i)hello").unwrap();

Output example

Regex

Code explanation

• Regex::new: This is a function from the regex crate that creates a new Regex object.
• r"(?i)hello": This is the regular expression that is passed to the Regex::new function. The (?i) modifier makes the regex case-insensitive.
• unwrap: This is a method on the Result type that is returned by the Regex::new function. It will either return the Regex object or panic if an error occurs.
