So I've started learning Rust and I must say it feels great! But some parts of the language, like enums, are quite different than what I'm used to.
As a proof of concept I've reimplemented a small API (an Azure Function App) in Rust with Actix Web and it's FAST AS FUCK BOIII.
The response is served about 5x as quckly and the memory footprint shrinked from some 90 MB to around 5 MB.
In my small scale usecase it's not a huge difference, but I think it can be massive at large scales...
What is your experience with Rust (at scale)?

I wish I could quickly reimplement the whole fucking CMS Of Doom™ in Rust... but no time and resources :(

I'm trying to deploy an Azure Function via Visual Studio. VS gives me this error:

Publish has encountered an error.
Publish has encountered an error. We were unable to determine the cause of the error. Check the output log for more details.

A diagnostic log has been written to the following location:
"C:\Users\myusername\AppData\Local\Temp\tmp16F8.tmp"

Let's check the log then!

"Microsoft.WebTools.Shared.Exceptions.WebToolsException: Publish has encountered an error. We were unable to determine the cause of the error. Check the output log for more details. "

Fucking piece of crap

FUCK YOU FUCKING AZURE FUCKING FUNCTIONS:

EITHER LIMIT MY NUMBER OF TCP CONNECTIONS (before violently crashing)

or

FORCE ME TO USE THE GODDAMN PORT-PISSING, BARELY-MULTITHREAD-USABLE, SETTINGS-IGNORING EXCUSE OF A PATHETIC BUILT-IN HTTPCLIENT ON FUCKING CRACK (Seriously .net people fix that shit).

But not both... both are not okay!

If your azure function just moderately uses outgoing Http requests you will inevitably be fucked up by the dreaded connection exhaustion error. ESPECIALLY if using consumption plans.

I Swear, every day i am that much closer to permanently swearing off everything cloud based in favor of VM's (OH BUT THEN YOU HAVE TO MAINTAIN THE VM's BOO HOO, I HAVE TO BABYSIT THE GODDAMN CLOUD INFRASTRUCTURE AS WELL AT LEAST I CAN LOG IN TO A VM TO FIX SHIT, fuck that noise)

I am in my happy place today. At least I'm having great success diving into minecraft modding on the side, that shit is FUN!

What the hell happened to the dotnet ecosystem in terms of stacktraces and async.

You used to be able to pin down your issues to the freaking exact line number using a stacktrace, but now im building a azure function and this is the crap im served when it blows up: How do you debug this?

Two years ago we took over this project which has been a nightmare to maintain. It's a set of netcore 2.1 webapps running on an on-prem windows machine. Everyone who has worked on it so far has quit, leading to two episodes of it being passed on with near zero handover.

Its function is fairly simple, so naturally we have been nagging to redo it and cloudlift it.

I was finally given one week to see how far I'd get, and had a poc running in Azure after one day; 4 apps in clean net6, SSO, and managed identities. The only thing lacking was setting up the authentication for third parties.

And... they still don't want "something new" when the old one works. Back to IIS and debugging windows event logs.

!rant

*reworks complete solution then publishes it to Azure*
"Okay, now let's debug"

*calls function, no response*
*directly opens function in browser*
Function host is not running.

Fuck.

*opens Insights*
System.BadImageFormatException
(additionally, it states that it couldnt load my main project or one of it's dependencies)

Shit, never even heard of that exception.

DDG: yo you're fucked, here, have 3 proper results
SO: lul thats some known bug Azure Functions havent fixed till now
Github: Yeah got a lot of open issues ok that, they just aint any help lmao

Me, a naive person: "okay lets try randomly changing some dependency versions, might help"

It didn't.

Now my question: how do I escape Dependency Hell?

Fuck VS! C# sucks! F# sucks!
I found no way to debug C # and F # without VS(At least the official did not give a plan)! And I can only use macOS now.
After downloading VS for mac, I found that it installed mono automatically! And there is not even a button to open the folder!
Why do you have to wrap a class outside the main function? And their pointers are not flexible at all! Also, unlike C, Go, and Rust, the compiled files are binary files. WTF does DotNet give me? debug directories and .dll files!
I originally planned to learn DotNet core for the convenience of using Azure.
But I found that, through Python, JavaScript, Ruby, C(LLVM-Clang), Go, C ++, Rust, Haskell, Azure can also be used, which gives me more sufficient reasons to give up C #, F #!
