I would assume that it would opportunistically try to run the borrow checker, and if it fails on the access of a specific field, turn that access into an Arc/Rc everywhere, leaving any other access as references. This leaves you with i

Adding scattered bike lanes in a haphazard way is insufficient. You need a network of physically separated bike lanes that connects an entire city. Any gap in the network makes it so the bike lanes might as well not exist, if you go fro

FWIW, if I had to avoid the `Result` return type and produce the `-1` sentinel, I would write fn add(str1: &str, str2: &str) -> i8 { let (Ok(a), Ok(b)) = (str1.parse::<i8>(), str2.parse::<i8>()) else {

I wonder if it could be a new manifestation of the long living problem of older resources appearing linked from random blogs or surfaced in web searches. I haven't seen that problem in a while, but could be one explanation for that.

I believe it is a case of "yes, and". A significant benefit of Rail transport is when you can go to the train station from your home by public transport, and when you arrive to your destination city in a place where you can take p

National governments have more considerations that purely saving tax payers' money, because such savings can be short sighted. Saving money on munitions during a war effort, for example. Would you be as eager to have your courtry'

An issue is immediacy: problems are better the earlier they are pointed out (why online errors are better than compile errorswl, which are better than CI errors, which are runtime errors). Having to copy paste an error adds a layer of indir

Funnily enough, trait bounds are still a big pain in the neck to provide good diagnostics for because of the amount of things that need to be tracked that are cross cutting across stages of the compiler that under normal operation don'

Elm is acknowledged as being the initial inspiration for focusing on diagnostics early on, but Rust got good error messages through elbow grease and focused attention over a long period of time. People getting used to good errors and demand

That would only work for projects that care only about current compilers, where C in general has more desire to support niche compilers. A mitigation here would be to make result of autoconf only provide instructions for humans to change th

From my experience looking at rust builds, Pareto applies here: most checks are trivial and used by a lot, and a handful are super complex and niche.

I think that listing behaviour could eventually be landed on rustc itself, but as it happens I am working on a listing tool, so I might just prototype it there first! The benefit of telling users "you can split this section off to its

I.dont think so, and I'm convinced that this could be done automatically as part of rustc, with the negative side effect of small changes that affect the splitting behaviour causing wild compilation time changes that are hard to debug.

That depends entirely on the implementation and use case. An append only arena, like is used in compilers, do not have ever invalid IDs by construction: you get the ID back after inserting into the arena and have no way of removing the valu
