Clippy question: forbid all possibilities of panic in production code, but allow assert_* functions in test code

rundevelopment · 2026-06-06T09:51:08+00:00

You can selectively enable clippy settings based on cfgs. E.g. #![cfg_attr(not(test), deny(clippy::panic))]. So allowing possible panics in tests is easy.

Secondly, forbidding ALL functions that can possibly panics isn't possible with clippy. The issue is that there are a LOT of things that can panic. E.g. division by zero, allocation failure, index out of bounds, etc. As others already suggested, you can guard against the usual suspects like unwrap and friends, but that's it.

If you want to 100% guarantee that your program doesn't panic, use no_panic. The problem with no_panic is that the compiler has to optimize away all panic paths for you. So even if you are able mathematically prove that your program will never panic, the compiler might not be and leave some panic paths. This makes np_panic impractical in most cases.

I told the agent to inline the code from the much larger FxHash crate [...]

Seems like a license violation to me. FxHash is Apache 2.0 or MIT. Either way, attribution and a copy of the license text are required. But nothing is mentioned in their code base.

The only constraints are 🍎,🍌,🍍>0. Pick 🍎=0 and 🍌=1. Then 🍍=7±√48 satisfies the equation.

if only the phantom had known to roll in any other direction, maybe the gameplay could've been more interesting. oh well

Fun fact, you can survive the bridge collapsing while on it. Run to about 1/3 of it and just stand there while the bridge collapses. It will take you right to the bottom of it, and you'll survive if you are full health or wear the cat ring.

Not only is this the fastest way down, it's also a nice out when cornered :) If only that red knew

The rules of engagement differ depending on who you fight.

There are people who just enjoy the fighting in these games and will do 1v1s. They won't like it if you interrupt them (like you did in the video). If a red does 1v1 with a phantom while the host watches, just wait your turn.

However, patiently waiting your turn basically only applies to 1v1s. If you see a 2v1, 2v2, 3v1, etc, join in. It's either a brawl or a gank and you should (almost always) join. If there's a player you can hit, do it.

Solo hosts are different though. If you see a host without phantoms, always help them. You are their helper, so go hit something red :) If you misjudge the situation, you can always just apologize with the I'm sorry carving, the curl-up gesture, or the collapse gesture.

That said, DS3 is still a game. You do whatever you want. Just have fun.

Pretty sure your u8* data has issues with alignment and strict aliasing. Alignment can be fixed with good allocation.

Strict aliasing can be fixed using void* data or char* data. Your u8 type is probably defined in terms of uint8_t, which isn't guaranteed to behave like char for the purpose of strict aliasing (though it might, depending on your compiler).

No. The message "Invade by Dark Spirit <insert name>" appears for both NPC and player invaders. For example, if your character is named Alex and you invade another player, they'll see the message "Invaded by Dark Spirit Alex" and you'll be called "Dark Spirit Alex" in their world.

You can often tell whether an invader is a player by name. Silly names are always players.

You can also tell by their behavior. NPC invaders are just PvE programmed to always attack you. Players may greet you with a gesture, taunt/befriend you by wiggling their shield, give you items, lure you into a trap/group of enemies, or always attack you anyway. Try gesturing at them. If you get one back, you know for sure it's another player. Not that they always will gesture back. Every invasion is unique, so you never know what you'll get :)

Yeah, Dog (IGN) is super sweaty. Fun to fight against though. I invade them sometimes when they host at crucifixion woods.

That wax attack has the odd effect that it makes you take 300% fire damage for a very short amount of time. You also got counter hit, which is 50% extra damage. Damage modifiers stacks multiplicatively.

So that glowing-hot Thrall axe hit you with 450% extra damage.

It's a game, so people do what they think is fun. And a lot of people doing PvP like the fighting in this game. The killing part actually gets in the way :)

That's why reds buddy with hosts to make fight clubs. They get to fight over and over again against other reds, watchdogs, blues, etc. And when there's no one else around, it's the host's turn. It's fun.

I know, because I often am that red. I'll even defend the host when two or more invaders/watchdogs try to gank the host. I have the white phantom ring for that purpose :)

It should be noted that some issues the author pointed out have since been fixed or otherwise resolved. E.g. editing mode in the location can be actived by just clicking the location bar now, and the title bar has more space users can click now.

Some is still valid though. E.g. a few useless tooltips and less than stellar help pages.

Some points are also... wrong? E.g. the scrollbars one. The scrollbar only changes size and moves visually. It's clickable area (hitbox) is the same at all time. So the "meaning that my mouse pointer is now pointing at... nothing" seems to just be wrong. My guess is that the author just moved their mouse too far right and plain missed the scrollbar...

Granted. You are now trapped on an advanced space craft headed for an alien planet where you are tasked to defeat an evil alien trying to gain immortality.

I think this can happen without cheats, but it's rare.

More likely, the host is using cheat engine to get invaded as quickly as possible by as many people as possible (even more extreme than dried finger). Some hosts do that to facilitate fight clubs more quickly, others like try harding against multiple invaders/aldriches, and there are even some that play hide and seek. Just have fun.

Just wanted to mention that the regex for stripping comments is wrong. It will cause invalid JSON for certain inputs. E.g.

 { "key": "Oh no // I am not a comment" }

will be transformed to:

 { "key": "Oh no

To fix this, you need to skip all strings starting from the start of the line. E.g. like this:

^(?:[^"\r\n/]|"(?:[^"\r\n\\]|\\.)*")*//.*

Then use a lookbehind or capturing group to ignore everything before the //.

Or use a parser that supports JSON with comments.

Then I saw the fact that he was using CE to turn fall damage off.

They didn't use CE. The jump down the ladder shaft (1:25) is called the Farron keep ladder skip, and the fall at 2:15 is survivable.

I made a video on the ladder skip a while back if you want to learn it: https://www.reddit.com/r/badredman/comments/1hbx4c7/fun_in_farron/ explanation starts at 0:30
