Lots more warnings are showing up on nightly compilers due to a recent change. I've opened rust-lang/rust#66373 on the compiler side for this as well.
Python 3 extension for interface with Wasmtime/Cranelift.
Build
First, you'll need to install some Python dependencies:
$ pip3 install setuptools wheel==0.31.1 setuptools-rust
Next you can build the extension with:
rustup run nightly python3 setup.py build
Note that a nightly version of Rust is required due to our usage of PyO3.
This will create a directory called build/lib which you can add to
PYTHONPATH in order to get import wasmtime working.
