前回、「Webassembly に入門してみた。 」の続編です。
前回 C 言語で書いていたところを Rust で実装してみるというやってみた系の記事です。
今回ハマるところがあまりなかった(OpenSSLくらい)のでただの記録記事になっています。
Rust でやってみる。
Rust は以下を`参照しながらインストール。

Could not find directory of OpenSSL installation, and this `-sys` crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it, you can set the `OPENSSL_DIR` environment variable for the
compilation process.
Make sure you also have the development packages of openssl installed.
For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.
If you're in a situation where you think the directory *should* be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl
