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.

Jasmine, A rust-like programming language that compiles to Java
I had recently completed the first year of my Computer Science class at school and will begin my second year soon. My schools' class forces the use of Java programming language, and I absolutely hated it. So, over the course of a little less than a month, I wrote my own programming language, in Rust (objectively best programming language), using pest, to be as similar to Rust as possible, but compiling to Java.

What is the state of the art for creating domain-specific languages (DSLs) with Rust?
I second pest.rs. Using it is fairly intuitive and there's also a live playground on their website which is great for quickly developing and testing your AST (abstract syntax tree) parser for whatever language you're implementing.

Finding a Crate to Help with Terminal Program Interface
This is where you'll run into trouble. People who write parsing-related Rust crates generally write things like pest that expect their syntax to be defined completely at compile time so the parser can be run through the compiler's optimizers for best performance.

What is your opinion about lifetime of data generated from a parsing
For now I have used pest to generate an AST that borrows from the given input. But if I can manage to make the parser generic over the return type it may be worth a refactoring.
- Is there a parsing library (lexer?) which can handle generic tokens?

nom > regex
I truly love Nom, it made parsing really fun. I suggest trying out https://docs.rs/winnow which is a fork of Nom with a lot of nice features, I find it much more usable.

What Vale Taught Me About Linear Types, Borrowing, and Memory Safety
I feel like I'll have to read up some more to have the background to fully understand the article but one thing I wanted to point out is a difference between `fn rand_int(rand: &mut Random) -> i64` and `fn rand_int(ran: Random) -> (i64, Random)`, at least in Rust. With the version that moves `Random`, the return type is bigger and may spill over from registers to the stack which may cause a significant slow down, more than the code of Vale's generation check, I suspect.
I've run into this with my parser combinator library, winnow [0], and am considering switching from the nicer functional model of moving to the more imperative model of `&mut` [1].
