This commit continues previous work and also #708 by removing the need to use `HostRef<Module>` in the API of the `wasmtime` crate. The API changes performed here are: * The `Module` type is now itself internally reference counted. * The `Module::store` function now returns the `Store` that was used to create a `Module` * Documentation for `Module` and its methods have been expanded.
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.
