Is there a way to configure Hyperscan to use only DFA state machines, or
otherwise restrict the time complexity of matches to be polynomial at worst?
We need to ensure the algorithmic complexity of our matches doesn't go
exponential in the size of the searched string, as NFA can for degenerate
We understand that this is incompatible with some regular expression
features such as backreferences.
I am looking to see if there is a way to get what the prefilter string
hyperscan is using for a given regex when HS_FLAG_PREFILTER is being used.
I tried looking, but could not find a way to do it.
