Please add samples for languages like Go and Rust

[jsoneaday]

It would be a huge help to have samples for those two very popular languages. Thank you.

Hi @jsoneaday,
here you can find all the known bindings and implementation of Node-API https://github.com/nodejs/abi-stable-node/blob/doc/node-api-engine-bindings.md.
For Rust you have many implementations and you can find some examples in the corresponding repositories.
I experimented on building the Go binding and in the last 2 weeks I started a new implementation.
