HashSet is a hash-based collection that allows only distinct elements

	<#
	The basics: A HashSet is a collection that holds unique elements in no particular order (O(1) complexity
	for adding, searching or removing). The HashSet<T> is a generic class in the System.Collections.Generic
	namespace, ideal for managing large data sets and performing set operations.

	Core aspects: The dotnet HashSet is a hash-based collection that allows only distinct elements.
	It supports various operations such as Union, Intersection, Difference, and more.

sassdawe / Write-FunctionError.ps1

Created July 4, 2022 06:09 — forked from JustinGrote/Write-FunctionError.ps1

Write an Error within a function in a nice way that displays the context of the function rather than the "Write-Error" context

	using namespace System.Management.Automation
	using namespace Microsoft.PowerShell.Commands
	function Write-FunctionError {
	<#
	.SYNOPSIS
	Writes an error within the context of the containing CmdletBinding() function. Makes error displays prettier
	.NOTES
	ScriptStackTrace will still show Write-FunctionError, so its not completely transparent. There's no way to "edit" or "replace" this stacktrace that I can find.
	.EXAMPLE
	function test {
