Question: Over all the Rust bindings, how cheap can we get a wasm process/vm to be ?
Longer question: Erlang has lots of very cheap non-OS 'processes', that (1) have per process heap, (2) communicate mostly with message passing, and (3) can crash independently.
I am wondering if there is some wasm runtime cheap enough to allow one to do something similar in Rust, where: (1) there are lots of wasm vm's, (2) these vm's have their own memory, and (3) these vm's can crash independently without effecting each other (or the 'host' rust application).
Question: over all rust/wasm bindings, how cheap can we get a wasm process/vm to be, and how does it compare to erlang processes ?
