Bumps regex from 1.12.3 to 1.13.1.

Changelog

Sourced from regex's changelog.

1.13.1 (2026-07-15)

This is a release that fixes a bug where incorrect regex match offsets could be reported. Note that this doesn't impact whether a match occurs or not, just where it occurs. The match offsets are still valid for slicing, they just may not refer to the correct leftmost-first match. See #1364 for (many) more details.

Bug fixes:

  • #1354: Fixes previously unsound reverse suffix and inner optimizations.

1.13.0 (2026-07-09)

This release includes a new API, a regex! macro, for lazy compilation of a regex from a string literal. If you use regexes a lot, it's likely you've already written one exactly like it. The new macro can be used like this:

use regex::regex;
fn is_match(line: &str) -> bool {
// The regex will be compiled approximately once and reused automatically.
// This avoids the footgun of using Regex::new here, which would
// guarantee that it would be compiled every time this routine is called.
// This would likely make this routine much slower than it needs to be.
regex!(r"bar|baz").is_match(line)
}
let hay = "
path/to/foo:54:Blue Harvest
path/to/bar:90:Something, Something, Something, Dark Side
path/to/baz:3:It's a Trap!
";
let matches = hay.lines().filter(|line| is_match(line)).count();
assert_eq!(matches, 2);

Improvements:

  • #709: Add a new regex! macro for efficient and automatic reuse of a compiled regex.

1.12.4 (2026-06-09)

This release includes a performance optimization for compilation of regexes
