RE2

RE2 is a software library developed by Google that helps computers process and search through large amounts of text quickly and efficiently. It implements regular expressions—patterns used for finding specific sequences of characters within text. RE2 is designed to perform these searches rapidly while ensuring that the search process remains predictable and safe, avoiding situations where it could slow down or freeze. It's widely used in applications like search engines, data analysis, and security tools where fast, reliable text pattern matching is essential.
