No.
Although I think it’s a symptom of a larger problem. At the very least, consider Rider (or for non-C# code, VS Code/Codium/your terminal editor of choice).
At work, we have to use VS for C# development though, due to us having VS licenses and not Rider licenses. I guess we could use VS Code for C# dev, but I could also use Morse code to type, and neither of those sound like a good time when you take our work tooling into account.
Without context, there’s no reason to compare the performance of these. The compiler is complex enough that what you do in the loop and after the loop matters with regards to optimizations.
Do you have more context? What’s actually happening in the code?
For #4: the 'de lifetime is the lifetime of the deserializer (and input data). It’s used to allow you to deserialize the data into a type without copying it, like deserializing a &'a [u8] buffer into a &'a str. It’s documented here if you want to read more.
Ironically, many languages that violate these rules are spoken in the US natively. People in the US just like to forget that there are other natively spoken languages (spoken since before English was introduced to the continent even).
English. I can go to the store and buy a sandwich for $8.99 all in one sentence, but splitting it on periods gives you two sentences.
Another couple missing:
A fun language to learn regarding these is Hawaiian, where the language uses a-class and o-class rather than masculine and feminine, and which you use is largely based on how much control you have over it.

For personal projects, I don’t really care what you do. If someone who doesn’t know how to write a line of code asks an LLM to generate a simple program for them to use on their own, that doesn’t really bother me. Just don’t ask me to look at the code, and definitely don’t ask me to use the tool.
