This project is a C++ API for Wasmtime. Support for the C++ API is exclusively built on the C API of Wasmtime, so the C++ support for this is simply a single header file. To use this header file, though, it must be combined with the header and binary of Wasmtime's C API. Note, though, that while this header is built on top of the wasmtime.h header file you should only need to use the contents of this header file to interact with Wasmtime.

Examples can be found online and otherwise be sure to check out the README for simple usage instructions. Otherwise you can dive right in to the reference documentation of wasmtime.hh
