Covers Cloudflare’s work to modernize Rust-based WebAssembly Workers so they interoperate better with Cloudflare’s large TypeScript API surface. Describes improvements made in collaboration with wasm-bindgen — including TypeScript-style generic JS typing, panic=unwind support for recoverable errors, and recoverable aborts — and gives an early preview of a new Rust Workers SDK.
