evcxr VS cargo-script

https://github.com/evcxr/evcxr/blob/main/evcxr_repl/README.m...

There is this if we really want a rust repl

A project for Rust REPL environment is a combination of letter evxvr (Evaluation Context for Rust). It contains Evcxr Jupyter kernel. I chose to follow the documentation and compile Jupyter kernel from Rust sources (which takes about 6 min on my laptop), and simply run in Microsoft Windows PowerShell

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:

Accept BTC, all credit card * $1 .unwrap() - wallhack through Err * $2 .ok() - invisibility cheat for unused Result warning * $5 .unwrap_unchecked() - advanced wallhack, never fall out of map from panic For script console, just $10.

You can also use cargo script. After installing it you can just do

I think there are some projects in this area, eg, https://github.com/DanielKeep/cargo-script. For my personal scripts, I have a single Cargo.toml for a busy-box style multiplexed binary: https://github.com/matklad/config/blob/f0259ca8a3755f2e62a3bf472c2514fd6cb891ff/tool/src/main.rs#L16.

O seems that this does already exist: https://github.com/DanielKeep/cargo-script

You don't have to set up a project if you use cargo-script

Take a look at cargo script. That should/could do what you want

when I first started using rust, I knew python a lot better so I would write scripts with python. at this point though, I write a lot more rust than python these days, so I'll write pretty much everything with rust. cargo-script is a useful tool for this, as well as the self-compiling script: https://neosmart.net/blog/2020/self-compiling-rust-code/

Another option is cargo-script, which lets you run self contained rust files.
