Development Environment

Follow the steps below to get an OpenDP development environment set up, including the ability to run tests in both Rust and Python.

Install Rust

Download Rust from the Rust website.

Install Python

Download Python from the Python website.

Clone the OpenDP Repo

Clone the repo and change into the opendp directory that’s created.

git clone https://github.com/opendp/opendp.git
cd opendp

Build OpenDP

Change to the rust directory before attempting a build, run the tests, and then return to the opendp directory.

cd rust
cargo build
cargo test
cd ..

Add –features=untrusted to the cargo commands to include non-secure floating-point and contrib features like make_base_laplace. If you are on Windows, [check the windows build instructions](opendp/opendp).

Install Python Dependencies

Change to the python directory, create a Python virtual environment, activate it, install dependencies, and then install the Python OpenDP library itself.

cd python
python3 -m venv venv
source venv/bin/activate
pip install flake8 pytest
mkdir src/opendp/lib
pip install -e .

The developer install will not work if you don’t use the -e flag when installing with pip!

Run the Tests

From the python directory, set an environment variable to the location of the OpenDP library you built. Then run the tests.

export OPENDP_LIB_DIR=../rust/target/debug
pytest -v
