Ah nice! I will definitely take you up on it one day!! 
For me Rust is most interesting for WASM, hopefully by the time I am ready to get into it things might have moved on a bit by then.
My current plan is:
- Programming Erlang
- Programming Phoenix
- Create a small-ish app in Phoenix
- See whether I need to read more Elixir/Erlang books or whether it’s time to check out Rust or Swift
Yew looks interesting - at some point it might be worth having a ‘State of WASM 2021/22’ thread 
While WASM isn’t the perfect solution yet, it can help developers create extremely fast web experiences. The Rust team is committed to a high-quality and cutting-edge WASM implementation. For developers, this means you could have the performance advantages of Rust (vs. Go) while still compiling for the web (using WASM).
Some early libraries and frameworks in this space:
