In rust the in order to see the expansion of the macros like println! we can use the rust-expand crate

First install the crate

cargo install cargo-expand

then use cargo expand command

[dependencies]
libc = "0.2"

extern crate libc;

use std::mem;
use std::os::unix::io::AsRawFd;

[dependencies]
quote = "1.0"

use quote::quote;

fn main() {
	let field1 = quote! { x: u32 };

SharedArrayBuffer is a feature in JavaScript that allows multiple JavaScript processes to share the same memory space. This can be particularly useful in scenarios where you need to communicate and synchronize data between different threads or processes efficiently.

In Node.js, SharedArrayBuffer is supported starting from version 12. It provides a way to share raw binary data across different JavaScript contexts, such as web workers, or in the case of Node.js, across different worker threads using the worker_threads module.

Here's a basic overview of how you can use SharedArrayBuffer in Node.js:

Creating a SharedArrayBuffer: You can create a SharedArrayBuffer using the new SharedArrayBuffer() constructor. For example:

const sab = new SharedArrayBuffer(1024); // Creates a SharedArrayBuffer with 1024 bytes

	#!/bin/bash
	# Wraps aursync command to mount an amazon s3 bucket which contains a repository
	set -uo pipefail
	trap 's=$?; echo "$0: Error on line "$LINENO": $BASH_COMMAND"; exit $s' ERR

	INTERFACE=wlp58s0

	wpa() {
	wpa_cli -i "${INTERFACE}" "$@"
	}
