This article explains how inline assembly semantics fit into the Rust Abstract Machine by proposing a "storytelling" approach: every inline assembly block must have a corresponding Rust code equivalent that describes its observable behavior, allowing the compiler to reason about soundness and apply optimizations correctly. The author demonstrates why inline assembly cannot arbitrarily violate Abstract Machine constraints like aliasing rules, even though assembly itself doesn't have these concepts.
A practical guide documenting patterns and conventions for writing Rust-based WebAssembly with improved ergonomics and safety, including type naming conventions (Wasm* prefixes for exports, Js* for imports), memory management strategies (using Rc/Arc over raw references), and best practices for managing the boundary between Rust's ownership model and JavaScript's garbage collection.
