This is a little proof of concept of using WebAssembly to distribute plugins. Currently it doesn't really provide true language independence because only plugins generated from Rust code via wasm-bindgen will work, but it's a start.
The plugins allow to dynamically add greeting messages in several languages.
Plugins provide two functions:
languagereturns the language as a string.greettakes a name and returns a greeting in the language.
Using strings forces us to deal with more involved operations than just using the WebAssembly basic numeric types.
english-rs is a Rust plugin returning a greeting in English.
i18n-greeter is the Rust code that actually loads the WASM files and run the greeting using a name given as argument. It currently expects that the function are called using the wasm-bindgen conventions.
