    public static final class RegexMatcher.GoogleRE2
    extends com.google.protobuf.GeneratedMessage
    implements RegexMatcher.GoogleRE2OrBuilder
     Google's `RE2 <https://github.com/google/re2>`_ regex engine. The regex
     string must adhere to the documented `syntax
     <https://github.com/google/re2/wiki/Syntax>`_. The engine is designed to
     complete execution in linear time as well as limit the amount of memory
     used.
    
     Envoy supports program size checking via runtime. The runtime keys
     `re2.max_program_size.error_level` and `re2.max_program_size.warn_level`
     can be set to integers as the maximum program size or complexity that a
     compiled regex can have before an exception is thrown or a warning is
     logged, respectively. `re2.max_program_size.error_level` defaults to 100,
     and `re2.max_program_size.warn_level` has no default if unset (will not
     check/log a warning).
    
     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.
