astro VS evcxr

Some people tried using Rust to implement programming languages, right now I do not know any bigger language with compiler written in Rust but there was an attempt with astro. Match statements make parsing in Rust pretty comfortable.

I have tried figuring out what the project even was - it was in Astro. After some googling and reading I figured out.... I better not go deeper. It's some kind of a niche language, which may even be fun and great, but isn't used most of the time and isn't even finished. So even if I have learned it (which would be hard, considering no documentation), I wouldn't be able to transfer my skills as easily to another project, since chances are - it's not in Astro.

Emacs didn't invent REPL, and it's common everywhere. For Rust: https://github.com/evcxr/evcxr/blob/main/evcxr_repl/README.m.... But heck, the compiler is reasonably fast enough that any IDE can REPL by compiling the code.

The value here is more in being able to read a script before you run it, then have it run fast, maybe tweaking something here and there. And a compiled script will run 10,000 times faster than LISP, which can be important.

https://github.com/evcxr/evcxr can run Rust in a Jupyter notebook. It's not Golang but close enough.

The engine uses rust_decimal::Decimal to represent high precision decimal numbers, like the weight property. Serialization of RocksDB keys is done by the storekey crate. To know how Yumi's machine stores diffs, we can now ask- How does storekey serialize rust_decimal? Well, using evcxr to run Rust in Jupyter, the answer is as a null-terminated string:

In theory you should be able to create Rust notebooks (Jupyter notebook) using evcxr so maybe some AI, data analysis, prototyping make sense if you aim for good performance in final application (protype in evcxr and use notebook as reference to implement final application in Rust for speed and safety).

You should check out evcxr

There is also implementations of rust REPLs, like the beautifully named evcxr.
