 To compile for WebAssembly, your clang has to recognize `--target=wasm32`. Alternatively you can build your project with `CC` environment variable set to `emcc`, the [Emscripten compiler](https://emscripten.org), and `AR` set to `emar`, naturally, with both commands available on your `PATH`.
 
-While `cargo test`'s dependencies happen to require at least Rust 1.65, the library by itself can be compiled with earlier compiler versions. Though in order to use Rust version prior 1.56 you would need to pin`zeroize` to "=1.3.0" and `zeroize_derive` to "=1.3.3" in **your** project Cargo.toml. And if you find yourself with Rust 1.56 through 1.64 as the only option and want to execute `cargo test` you'd need to pin some of `[dev-dependencies]` versions in **this** project's Cargo.toml:
