Proof-of-concept of calling a Numba jit'd function from Rust from Python using CFFI
This example defines a function in Rust that doubles the result of the function passed to it. The Numba @cfunc decorator with CFFI support
requires Numba 0.27. This allows Numba to create a C callback that can be passed
to Rust.
Basic instructions for running the example:
If you need to install numba, then I recommend first getting Miniconda and then:
conda create -n rust-numba-example cffi numba numpy
source activate rust-numba-example # or just `activate rust-numba-example` on Windows
Then to compile the Rust code and run the python example:
cargo build --release
python test.py
