For reference somewhere, to update deps:

$ make requirements  # upgrade requirements.txt via pip-tools
$ cd autopush_rs  # TODO: put the remaining commands in the Makefile
$ cargo install cargo-edit   # if you don't have it already, provides "cargo upgrade"
$ cargo upgrade  # upgrades Cargo.toml
$ cargo update  # updates Cargo.lock
$ cd ..
$ python setup.py develop  # rebuild autopush_rs
$ nosetests  # ensure it still works..
