If you're thinking that this is an article about 'Bare Metal WASM' as an OS sandbox, you should probably think again; Hard.<p>> This post will cover the process of creating tiny graphics demos without doing any binary hacking, hex editing, or writing WASM by hand.<p>So nothing about actual 'Bare Metal' using WASM. Just Rust cross-compiling to WASM using 'wasm-unknown-unknown'. Title should be 'Cross-compiling web apps to WASM.' rather than this misleading title.
