typeshare-driver
This crate contains a macro generating all the glue code necessary to create a typeshare binary. Supposing you had your own Python and Golang implementations of typeshare, all you need to write is this:
use typeshare_binary;
use Golang;
use Python;
typeshare_binary!
This creates an fn main that uses these languages, plus typeshare-engine, to implements a full typeshare CLI.
