Regex::match_() panic on non-matching input in debug builds

[micaiah-effiong]

When using glib::Regex::match_() with an input string that does not match the pattern, the function panics in debug builds due to an incorrect assertion.

use glib::prelude::*;
use gtk::glib;

fn main() {
    let rx = glib::Regex::new(
        r"\d",
        glib::RegexCompileFlags::DEFAULT,
        glib::RegexMatchFlags::DEFAULT,
    )
    .unwrap()
    .unwrap();

    // This works (matches)
    let input = glib::GString::from("8");
    let _ = rx.match_(input.as_gstr(), glib::RegexMatchFlags::DEFAULT);
    println!("Matched '8' - OK");

    // This panics (no match)
    let input = glib::GString::from("a");
    let _ = rx.match_(input.as_gstr(), glib::RegexMatchFlags::DEFAULT);
    println!("Matched 'a' - OK"); // Never reached
}

Expected Behavior

match_() should return None when the input doesn't match the pattern.

Actual Behavior

Panic in debug builds:

panicked at /Users/me/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/glib-0.21.3/src/regex.rs:180:13:
assertion `left == right` failed
  left: true
 right: false

Environment

glib-rs version: 0.21.3
OS: macOS

Am I using match_() incorrectly? I expected it to return None when there's no match rather than panic. Any help would be appreciated!

No, the bindings are wrong because the C function is behaving non-standard. Will fix, thanks for reporting :)

See #1849 and maybe you also have an opinion for my question there
