Is deku fast? #288

Closed vext01 closed 2 years ago

vext01 commented 2 years ago

Hi,

Do we have any idea if deku generates fast parsers?

Cheers

I have done some work recently to improve the speed of the deku generated parsers.

We don't have benchmarks against just writing a parser by hand. My only note is that if you are only using this to parse bytes then your performance will suffer quite a bit, as our backend bitvec works on bit slices.

See #25

There are some trade-offs, yes. Not to say these couldn't be solved given some effort / time. I would recommend doing comparisons/benchmarks yourself and see if it meets your requirements.

Fast is relative.
