Thanks for the correction 👍

Thank you again and I will.

Exactly the same. Kicking of the binary now, but library could solve a lot of the security issues I was worried about.

Not talking threads here, more Tokio tasks.

DUDE!

You are the man!

I did know it was built in rust but never realized I could also use it as a library!

🎉

It is now quite clear that I have to let go of OO paradigms. Maybe the package approach is perfectly fine.

Thank you for the insights and useful answer!

I have the idea that I am still only scratching the surface of rust, although I seem to manage it better every day.

As long as I leave my OO hat on the rack 😉

Well. I did read up on the “XY” problem and apparently you assume that what I want to do is somehow bad practice.

To elaborate more on the problem: I am writing an axum backend which (like other backends) needs to do stuff in the database. As some endpoints update the database (and sometimes over multiple sql statements) I want to pass around the transaction as this embodies the connection I am using to update the database.

To separate the axum stuff (parameters, urls and whatnot) from the actual database logic, I’ve first pulled out all the database interactions into separate functions. Because those functions are logically groups (e.g. stuff happening with invoices, others with contacts etc), I thought it was a good idea to create a “dao” struct (and agreed: my OO brain kicked in here which might be debatable). This would group the interactions for each logical domain into a short-lived data access struct.

To prevent passing around the transaction/connection, i wanted to pass that along during construction, so the functions in the DAO could just access the connection when needed.

Non “OO” would be fine to be honest (just having all the DAO as functions in a separate package).

Sorry, no code, not at the computer atm.

(And yes, I am aware that rust is not OO, put away the pitchforks please 🙏)

Thanks! Will try that!

Seems like the into_inner is the way (i see other references to it).

And yes, transactions should be short-lived, this is just about delegating it to the responsible component.

So your answer is “you are doing it wrong”.

Thank you, very helpful 😉

Actually quite relaxing to create patterns on this! Great tip!

You, kind sir, deserve a reward.

Bravo!

I am currently using it from a backend to generate pdfs.

One thing that prevents me from letting users build their own templates is the scripting capabilities. A joker creating an endless loop could block the whole server.

What would be nice is a “safe” mode in which no access to the file system (include and sorts) and limited runtime makes it safe to let users build their own templates.

Don’t let the door hit you on the way out.

Amazing way to approach it!

Just a wee bit afraid there would be just porn left after applying the “subscribe to me” rule 😉

I was an avid nginx user but having caddy handle the ssl certificate creation and renewal is amazing.

I probably am outdated on nginx (maybe it supports it?) but caddy is what I use from here on out.

Dude. You are ranting.

Find help.

Russia, as imperialistic aims it may have, have no intentions, not capabilities of invading Poland, Lithuania or Finland.

Hey, I’ve heard that before in 2014. You know the three day invasion?

And because I really think you are a troll: the best part is, NATO has yet to set foot on the ground, while Russia is running to rogue countries like NK.

Besides, Ukraine being “awkwardly neutral” did not stop Putler from invading, did it?

You use a lot of words, but a foundation of your “facts” are blatantly missing.

Don’t know what it is in this thread. “It did not work for you so you must have done something wrong”?

See my thread where some dude says it should just work (when he is just doing LTS kernel updates only and not updating in general).

Comments simply blaming the user based on their limited usecase are hardly constructive.
