Rust: Dropping heavy things in another thread can make your code 10000x faster

Most compiler are not designed to run in daemon mode, specifically it's non-issue since their startup is normally fast. And the compiler and runtime are a different thing.

I realise that, but nowadays language servers are a pretty normal practice in no small amount of areas.

You mean like LSP? Why would a compiler and a language server be integrated in the first place? Clearly a LSP server wouldn't use a no-freeing strategy, but there's no reason why it would cause issue with a compiler. A compiler must terminate, assuming parsing isn't turing complete (like Perl) and that the source code is finite. This is why it's okay for it to leak memory.

Because a language server needs to do a lot of the same work as a compiler.

This is an eventual hope for rustc. For now, the latest language server and it share a bunch of libraries, but language servers are effectively compiler frontends.

Yep, I guess I conflated compilers and LSP. I imagined compilers would have daemon modes. Seems like I was wrong.
