Implementations

Rust wasm32-unknown-unknown target - Rust compiler backend for WebAssembly (without the need for Emscripten).
Wargo - a simple npm package that makes compiling Rust to WebAssembly easy on macOS or Linux.
RustWasmLoader - A simple Webpack loader that shells out to cargo to build a Rust project targeting WebAssembly.
CargoWeb - This cargo subcommand aims to make it easy and convenient to build, develop and deploy client-side Web applications written in Rust.
Wasm-Bindgen - A library and a CLI for Rust that facilitate high-level interactions between wasm modules and JavaScript.
Woz - Woz is a WebAssembly progressive web app (PWA) toolchain for building and deploying performant mobile apps with Rust. Distributing your app is as simple as sharing a hyperlink.

Verus: Verus is a tool for verifying the correctness of code written in Rust. The main goal is to verify full functional correctness of low-level systems code, building on ideas from existing verification frameworks like Dafny, Boogie, F*, VCC, Prusti, Creusot, Aeneas, Cogent, Rocq, and Isabelle/HOL. Verification is static: Verus adds no run-time checks, but instead uses computer-aided theorem proving to statically verify that executable Rust code will always satisfy some user-provided specifications for all possible executions of the code.
