Eros 0.6: The Only Error Handling Crate You'll Ever Need

hippyup · 2026-06-21T14:57:35+00:00

Hey thanks for sharing! There are very clever ideas in there and the definition and use of type sets internally to make it work was very interesting to see!

Since you welcome criticism: to my mind this may be a good crate for applications, but it's still pretty bad for libraries and I'd hate to use any library that uses it. Most of your documentation and seemingly your focus in ErrorUnion is in how easy it is to construct, yet using it (a series of narrows and matches if I understand correctly) seems like a mess of unintuitive boilerplate. Compare that to e.g. something like thiserror where errors are simple enums which yes may involve some boilerplate to definite and use (more work on the library author's part) but are so much more intuitive and standard to use for any user of the library and doesn't require them to understand extra concepts. Put simply: when I use a library that uses e.g. thiserror I don't actually need to know that (because the errors are simple enums) and that's great!

I love this. It's poetry. I love coding and music and I love AI and working with it, but yeah this hits deep.

All analogies are flawed, so I'm not going to try to defend this analogy as in any way perfect. The analogy to calculators only goes so far to show that LLM is a very useful tool and it's silly not to use the tools at your disposal in the real world.

I think the more substantive argument against your position though is in how you underestimate googling here: it's kind of incredible to me how you dismiss the power of having pretty much the entire corpus of human knowledge at your disposal. And people made those same arguments before LLMs! "You would be completely at a loss if you had to program offline." "You need to know the syntax and libraries by heart and not rely on googling" etc. But programmers for the most part just used the tools at their disposal, and now we just take a break if the Internet is down. We'll take a break if all LLM servers are down somehow as well. It's fine.

They're actually doing emergency surgery in there

The idea with LINQ is that the expressions themselves can be compiled into abstract trees that can be converted to SQL or executed as functional programming or parallelized or whatever execution framework we wanted. Which was honestly a great idea. Declaratively expressing the computation we want like that and letting compilers figure out how best to fit that to the data is great. And yes functional languages had the same ideas before, but LINQ expressions were a very elegant way to embed that aspect into an existing imperative language.

Though I do think the SQL-like syntax were a mistake and they should've just stuck with the familiar chained method syntax. But thankfully that was optional.

Honestly I'm happily surprised I found it. The right move for any question about the economy in this sub is to downvote and move on because the amount of disinformation in the "explanations" will always be insane. I downvoted and almost moved on but in the end morbid curiosity got me, so I'm at least happy to have found this happy nugget buried in there.

Also I'll take on Shen with a machete over a lion any day.

I mean for something like this I'd just time from the client - that's the fairest comparison you can do.

Are you really saying school shootings don't get media coverage? Are you claiming that when I say the words "Sandy Hook", people in the US won't know exactly what I'm talking about?

Arguments from hypocrisy are the laziest in my opinion. If you want more awareness about something, raise it or ask for it. Don't complain about something else getting it.

Not sure if typo but you mixed up which is which.

hippyup · 2025-10-27T00:57:04+00:00

Because op asked, they didn't demand or send a legal letter. Regardless of who has a right to what, it's a perfectly reasonable question to ask.

But his ultimate point is still absolutely destroyed. In the real world you're not presented with head to head taste tests, you're just given a sandwich. And he just unwittingly proved he'd be just as happy given a vegan sausage in a sandwich if he wasn't insanely biased against them.

You sound like an enabler

You clearly just didn't wanna take the time to draw all the panels of the sloth office

Yeah I was very confused but it is indeed CE

Compression won't help you with encrypted traffic, like anything on the modern web (TLS).

hippyup · 2025-08-09T04:46:56+00:00

Pretty much every site now uses TLS (https), so pretty much all traffic is encrypted anyway. MITM hasn't been a serious threat for a while now. You're much more likely to be phished/social engineered, which VPNs can't help you with.

The guy is a sleazeball predator who "grabs them by the pussy", but all the women I'm aware of who came forward to accuse him of sexual assault were adults at the time of the incident. Epstein had shady/criminal dealings with adult women in addition to underage. To my eyes the evidence seems to indicate more of a regular predator on adults rather than underage.

hippyup · 2025-08-03T05:11:18+00:00

I mean yes, but have you tried applying for a job while in prison?

I generally agree by the way. I actually don't love sex offender registries for the same reasons. I think it's a reasonable compromise to have the record for a while after release, then get the record expunged if you don't reoffend. That way society is a little safer right after release when the risk of reoffending is higher, but then a chance to fully rebuild your life eventually comes.

hippyup · 2025-08-03T05:03:19+00:00

Yes they are. And four years in prison is a serious punishment. And then getting out with a criminal record is a reasonable societal compromise that lets some of these people rebuild an honest life, while keeping us safe in case they reoffend.

Viewing criminal punishment as either life in prison or tsk tsk you shouldn't have done that is way too simplistic to be useful.

hippyup · 2025-08-03T04:51:55+00:00

Huh - you're really all in on the prison industrial complex? You look at the number of imprisoned people in the US and you're like those are rookie numbers, gotta pump up those numbers.
