socket2 lib not compiling

Hello, I was working through chapter 2 and wanted to check my work, and when I downloaded the project from GitHub.
I received this error, it seems to be low level in one of the dependancies.

Does anyone know how to fix it?

error[E0512]: cannot transmute between types of different sizes, or dependently-sized types --> /Users/mycomputer/.cargo/registry/src/index.crates.io-6f17d22bba15001f/socket2-0.3.12/src/sockaddr.rs:176:9 | 176 | mem::transmute::<SocketAddrV4, sockaddr_in>(v4); | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: source type:SocketAddrV4(48 bits) = note: target type:sockaddr_in` (128 bits)

problem with persist_in() function for awmp.

the persist_in() function only takes the /temp directory provided by std::env::temp_dir(). Is there a way to change the default temp directory?

Chapter 6 NodeJS build error

Going through the WebAssembly+NodeJS exercises in the last chapter and ran into the following error when attempting to build the NodeJS project:

$ npm run build

> [email protected] build
> webpack --config webpack.config.js

node:internal/crypto/hash:71
  this[kHandle] = new _Hash(algorithm, xofLen);
                  ^

Node.js v18.7.0

After a bit of Googling, I ran across someone suggesting to run the following command:

$ export NODE_OPTIONS=--openssl-legacy-provider

Then run the build command again, and it should all compile.

$ npm run build

Not exactly sure what would be the proper fix here but using --openssl-legacy-provider unblocked me.
