On “Should I create a reference when getting value from a Option<&SomeStruct>?”

…etime of all references in an annotated group (such as `'a`) and just uses it as a hint to figure out how long a reference is expected to live. Lifetime annotations don't CHANGE the lifetimes at all. It just helps the compiler figure out complex borrowing. His explanation doesn't teach the viewer ANY of that. Btw, there's a great video on YouTube: link to this video - When he first attempts to explain Error Handling, he says that he's "propagating unhandled errors back to the caller", but his code example swallows the unhandled errors and just debug-prints them silently (no propagation). He actually has a chapter after that about how to propagate errors, but why did he decide to confuse the students by…

On “My learning journey with Rust as a 20 YOE dev”

Lifetimes: [video Async: [video Bogdan's videos have I don't profess to be an expert - I'm still learning rust, but I absolutely see the benefits of rust. There are unfortunately plenty of drawbacks too. The ecosystem people use is all over the place - competing crates, with names that aren't intuitive some of the time. If you really want to deconstruct then you should look at converting your code to assembly language and see how it works under the hood. I get what you mean though - you want to understand what the rust compiler is doing under the hood, *why* things work in a certain way. The difficulty is that with many languages these days (eg rust and java / spring) the…
