Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Cryptoflow: Building a secure and scalable system with Axum and SvelteKit - Part 0
I used cargo-watch here so that every time my source changes, the server will automatically restart and re-serve the updated code.

Functional Programming 1
Rust: RPDS https://docs.rs/rpds/latest/rpds/ and Im https://docs.rs/im/latest/im/
Rust isn’t great for letting you do FP things like other languages, but it does have the best type system imho which makes it the leading functional programming language right now imho. If you’re not using too many specialized python packages then I recommend using Rust instead, even for toy demos, as you can be more confident your code works without needing to run it and wait for a crash like you would in debugging python, and the tests also run faster in rust due to the incremental compilation. Use cargo-watch and you can retest your code every time you save your work.
https://github.com/watchexec/cargo-watch
I usually write a make command to cargo watch and rerun each test file : code file pair independently so then you won’t rerun your tests in other modules when you change the one you work on (faster but might miss stuff if you change API contracts which touch other parts of your codebase)

Are there any continuous testing tools with real-time line-by-line IDE feedback for Rust?
you can use cargo-watch to real time run tests on save in your attached vs code console session which is about as close to what you're asking as I think exists for rust

Why does the "crate" nomenclature include both "binary" and "library"?
Note that cargo, by virtue of being a package manager for a programming language, is primarily going to be dealing with library packages. That's not because it can't manage executables (see cargo-watch for a particularly useful example), it's just that it's less common.

cargo-watch hangs on reload
Unless there's a new issue, I think this is what was here: https://github.com/watchexec/cargo-watch/issues/249

Creating Rest APIs with Rust
A feature that I look for whenever possible in my development environment is Hot Reload, with it, every time a file is changed and saved the application restarts, so the cycle of writing-evaluating-refactoring code becomes extremely fast, for Rust, we have cargo watch, I suggest taking a look at the documentation for more details.

Scriptisto: "Shebang interpreter" that enables writing scripts in compiled langs
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.

Go: What We Got Right, What We Got Wrong
https://github.com/evcxr/evcxr can run Rust in a Jupyter notebook. It's not Golang but close enough.

The Hallucinated Rows Incident
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:
- TermiC: Terminal C, Interactive C/C++ REPL shell created with BASH
- Exploring Options for Dynamic Code Changes in Rust without Recompilation (hot reloading)
- Go 1.21 will (likely) have a static toolchain on Linux

What’s an actual use case for Rust
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).

would you use rust for scripting?

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