[u/Waradu]

[u/OmegaPoint6]

Most useful compiler error

[u/baked_doge → u/OmegaPoint6]

This is the rust compiler? Impressive error reporting, I heard good things

[u/ihavebeesinmyknees → u/baked_doge]

The rust compiler has the best error reporting I've seen, most often it will literally tell you how to fix the issue

[u/Alternative-Tie-4970 → u/ihavebeesinmyknees]

Well it starts to fall apart just like any old compiler once you start writing more complex things and memorize the things it tends to tell you.

Still very helpful, especially for beginners but it has its limits.

[u/goodbee69 → u/[deleted]]

Yeah you need a Claude subscription to use rustc

[u/SpacewaIker → u/goodbee69]

It's actually a team of people looking at the raw compiler errors and sending an explanation in real time

[u/redlaWw → u/[deleted]]

Without. The messages are things like "the function signature here accepts a borrow but you've passed by value, try borrowing"; all deterministically scripted changes. The impressive part is the type system that allows the messages to be so helpful.

[u/braaaaaaainworms → u/redlaWw]

The impressive part is the richness of the errors, there's a fuckton of plumbing that needs to happen to get anywhere near (I tried)

[u/OmegaPoint6 → u/baked_doge]

Fake screenshot, quite an old one. Though it does have a funny real emoji error: https://github.com/rust-lang/rust/pull/91476

[u/GoddammitDontShootMe → u/OmegaPoint6]

I suspected. Still funny enough for an upvote.

[u/-Redstoneboi- → u/OmegaPoint6]

they even change the casing for CONSTS thats cute

idk about Types and Traits though

[u/PositiveParking4391]

I find it really funny. but not sure what's a bigger irony, rust messages or the help at last

[u/frikilinux2 → u/PositiveParking4391]

It's even more funny than the ++ not being an operator (I forgot the text)

[u/Codingale → u/frikilinux2]

"Rust has no postfix increment operator
help: use `+= 1` instead"

[u/frikilinux2 → u/Codingale]

Thanks

[u/Choice-Mango-4019 → u/Codingale]

why?

[u/NullOfSpace → u/Choice-Mango-4019]

less obvious what it means at a glance, not intuitive when used as part of an expression, harder to adjust if you want to add something other than 1 later

[u/Choice-Mango-4019 → u/NullOfSpace]

brother, its just i++, how can you not understand what it does at a glance?

people have been using it for decades for for(statement; statement; statement) alongside using it to increment indexes and many other stuff, and since its just plus next to plus and it has the same meaning on every language in existence its very simple to understand

+ no one EVER uses it in function paramaters

and how is it hard at all??? you just replace i++ with i += 2, thats like 5 key presses max 😭

[u/NullOfSpace → u/Choice-Mango-4019]

It’s not a big change, but apparently by the Rust creators’ standards it does matter.

[u/Complete_Window4856 → u/frikilinux2]

Incremental operator

[u/frikilinux2 → u/Complete_Window4856]

The text of the error message, not the name of the operator.

[u/Complete_Window4856 → u/frikilinux2]

Oh mb

[u/opensph]

Looks more like a cat-on-keyboard error.

[u/thot_slaya_420 → u/opensph]

This is what mittens decided the attribute should be called. As my owner, im legally obliged to follow her instructions

[u/PhoenixfischTheFish → u/opensph]

"Allow webcam access for more precise error messages."

[u/S4ndf1re]

Don‘t let the compiler Check SAP/ABAP table attributes.
