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.
