I like 'ruthlessly'. It sounds very butch, especially applying to an activity largely carried out by seated, balding men hunched over terminals in an office.

Rust regex is suited to wide scale use. By comparison to Hyperscan, it is not suited to the kind of large scale cases that Hyperscan handles, but it's well done.

Many of Hyperscan techniques are sui generis, not published. Hopefully some of that will be rectified over time.
