I've never used the library directly but it was quite usefull as a method for hyperparameter search on optuna (for choosing machine learning tuning parameters).

There is an app built around this concept called Bitmessage, but I think it's abandonware now.

You can enable optional features on Rust analyser. For example, to enable ssr Leptos feature on VSCode, you'd need to create a .vscode/settings file:

{ "rust-analyzer.cargo.features": [ "ssr" ] }

Currently, though, you cannot enable the incompatible "hydrate" feature at the same time, sadly.

That's a fair point, although there is a simple solution in Rust (and other RAII languages) to use heap allocation if what you want is moving big chunks of data (so only the pointer is moved) or in case you really want copies, reference counting (Rc/Arc in Rust).

AFAIK, memory safety and language features as RAII is also available in C++, for instance. About the reasons for slow compilation, take a look at https://www.reddit.com/r/rust/comments/xna9mb/why_are_rust_p...

Not having a GC is also about not having a runtime as you mention (e.g. nice for creating Python extensions and embedded systems programming) and also more runtime deterministic performance: on that, if I'm not mistaken that was the reason for Discourse switching to Rust and also, e.g.: "the choice of Rust as the main execution language avoids the overhead of GC pauses and results in deterministic processing times" https://github.com/apache/arrow-ballista/blob/main/README.md
