[tor-commits] [tor/master] Initial code to parse/encode/sample prop271 guards
commit dd6def5daf5b0b579a61c9e83cfa905b333f99a1
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date: Mon Nov 14 15:46:09 2016 -0500
Initial code to parse/encode/sample prop271 guards
The encoding code is very straightforward. The decoding code is a
bit tricky, but clean-ish. The sampling code is untested and
probably needs more work.
