Rust embedding test

a toy example of hot to embed rust code into python.

Directory layout:

  • ./rust contains the rust code that complies to a unix shared library
  • ./cython contains the cython example binding
  • ./ctypes contains the ctypes example integration (alternative to cython)

Requirements

  • Rust:

    • cargo 0.15
    • rustc 1.14

  • Python 3.5+

  • Cython 0.25.2+

Building

Rust:

  • activate the cargo env with (optional)

      source ~/.cargo/env

  • run

      cd rust && cargo build --release ; cd -

  • add library to library search path

      export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`pwd`/rust/target/release/

Cython

cd cython && ./build.sh ; cd -

Testing

Make sure you add library to library search path

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`pwd`/rust/target/release/

Ctypes version:

cd ctypes && python embed.py; cd -

Cython version:

cd cython && python -c "import embed; embed.test()" ; cd -
