> It's possible that this is a compiler bug. It's also possible that there's some fringe case where the reference actually can escape via that method call, and the compiler doesn't have enough context to rule it out.

In the strictly technical sense I agree, however in the Rust community when people say "the niche optimization" they usually are referring only to the simplest case. For example in the book Rust For Rustaceans (written by a pretty

Really interesting technique. I guess one of the (theoretical?) drawbacks is the memory usage is not ideal? In a traditional bytecode compiler the result of compilation is a very-cache-friendly binary array, whereas here it looks like a vec

I think that a significant cause of homelessness is unaffordable housing. In 2025 housing affordability is better in Republican-run states like Texas because the state governments allow more housing to be constructed. Because housing is mor

The main reason they can't get housing though is that the government of California, which is dominated by Democrats, refuses to allow sufficient housing construction to make housing affordable.

Yes. At these latitudes there are times of the year when it's always night or always day. This messes with the math such that the graphs look weird.

Rust has this, and it just makes so much sense. Especially when you write a library in which the basic demo is also the basic unit test you want to make. Instead of writing a specific unit test that's hidden in source code, you just em

I agree that Trump's move was very bad, but we know that Biden didn't need a new law to "fix" the situation at the border. After Trump blocked that law, Biden made the executive order that for years he claimed he couldn&

I don't see why the code is not "learning safe". The code presents the simplest safe way to handle an OOM condition. Seems basically perfect for a _beginners guide_ to manual memory management.

by returningfory2 2y ago
The code in the article is not wrong. It is not unsafe. The author explicitly handles the OOM case correctly. It is true that there are more optimal ways to do it if you do have an OOM handling strategy. And no, you're not supposed to

It's a beginners article about memory management. I think it's weird that so many comments here are judging the code snippets as if they're commits to production systems. When writing articles like these there are pedagogical

I feel like this comment is misleading because it gives the impression that the code in the article is wrong or unsafe, whereas I think it's actually fine? In the article, in the case when `tmp == NULL` (in your notation) the author ab
