The impl is too complex, just pass flag str to regress::Regex::with_flags is enough, the error is expected, if user pass some flag regress don't support

What you only need is handle flags for regex https://docs.rs/regex/latest/regex/#grouping-and-flags

Should I verify the repeatability of flags for regex or let regex handle it?

No, just let lib handle it, the order does not matter.

In addition, I changed the confusing name source to pattern.

Also could you add a basic test to ensure regression?

mod test {
  #[test]
  fn with_flags() {
    let reg = super::HybridRegex::with_flags("a", "i").unwrap();
    assert!(reg.matches("A"));

    let reg = super::HybridRegex::new("a").unwrap();
    assert!(!reg.matches("A"));
  }
}
