The post itself may be good or bad, I don't know - but I just can't bring myself to read their happy-go-lucky banter.

#3Rust newbie here. How do you fix the compile error for the example given? I imagine it has something to do with transferring ownership, but I’m not too sure.

#4I think one of the biggest benefits of Rust is it bakes in static analysis of code as a first class feature. Which means the language is amenable to analysis and you don't have to use third party tools to benefit from it.
I also like some of the abstractions. They're clever in their simplicity. For example, an iterator over an array or vector is simply doing a for loop using pointers.

What "deepening crisis" is this?
Is it just the usual internet drama with a few people being unpleasant to each other and then storming off in a huff, or something more serious?

Lots of these things that look like syntax problems are in fact design problems surfaced by the compiler.
The `nickname` variable holds onto a reference to the substring of `name`. Subsequently `name` is modified (cleared).
This forces you to think about the behaviour. Should the nickname remain constant even if the backing `name` string changes? Probably yes, so you'd take a copy at that point.

I'd like to understand what you mean by baked in. Not only does vscode need a plugin, it needs a language server running to do the static analysis. Are there analysis capabilities without the language server?

The easiest fix is to clone the String, then build a slice from the copy.

The compiler by its self can do it, if you run it.
I believe the language server is just for real time editor integration.
