// [#protodoc-title: Google RE2]
// [#extension: envoy.regex_engines.google_re2]
// Google's `RE2 `_ regex engine. The regex string must adhere to
// the documented `syntax `_. The engine is designed
// to complete execution in linear time as well as limit the amount of memory used.
//
// Envoy emits two stats for tracking the program size of regexes: the histogram ``re2.program_size``,
// which records the program size, and the counter ``re2.exceeded_warn_level``, which is incremented
// each time the program size exceeds the warn level threshold.
