(#45875498)
As a means to get into WebAssembly and Rust, I started writing a binary decoder (i.e. a parser for `.wasm` files) from scratch.
Recently it hit v2.0 spec conformance. 3.0 is next on the roadmap. (I'm executing it against the upstream spec test suite.)
My aim is probably not for it to become a highly-performant decoder for use in production environments, but rather one that can be used for educational purposes and/or debugging issues with existing modules. That's why I decided not to bother with offering a streaming API, and why I'll be focusing on things like good errors, good docs etc.

P.S. I'm new to the language so any feedback is more than welcome.
