The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Spotting and Avoiding Heap Fragmentation in Rust Apps
I'm not sure if it's widely used, but Mesh is a C/C++ library that can recover from memory fragmentation. The YouTube video in the README is a great watch.

Compacting the Uncompactable: The Mesh Compacting Memory Allocator

Bizarre memory leak caused by tokio runtime
With everyone talking about memory fragmentation, I'd like to mention Mesh, an allocator that can compact aka defrag the heap without any help from the program or compiler. Here's the talk explaining it, "Compacting the Uncompactable" by Bobby Powers.

loxcraft: a compiler, language server, and online playground for the Lox programming language
rust-langdev has a lot of libraries for building compilers in Rust. Perhaps you could use these to make your implementation easier, and revisit it later if you want to build things from scratch. I'd suggest logos for lexing, LALRPOP / chumsky for parsing, and rust-gc for garbage collection.

What would be your programming language of choice to implement a JIT compiler ?
There's nothing stopping you from doing that in Rust. See rust-gc for an example of a GC implemented in Rust. Another example is mozjs, which is Rust bindings to SpiderMonkey. The GC there is implemented in C++, but it shows how you'd structure wrapper types for GC'd pointers in Rust so that you can use them safely, even with all the "ugliness" of a browser-grade GC.

One can have a GC as a library, https://github.com/Manishearth/rust-gc

Hey Rustaceans! Got a question? Ask here (7/2023)!
The ones I am aware of are gc and broom. None will be as simple to use as the one in old Rust as userland implementations don't have the benefit of first-class integrated compiler support.

Chris Lattner on garbage collection vs. Automatic Reference Counting (2017)
Rust has rust-gc, which is an attempt to add opt-in GC over Rust's more traditional automatic memory management. It's a neat project, but I'm not sure where it's actually being used.

I have programming skills! I am good at dealing with programs!
Inb4 "already exists": the question is about making it convenient, not just imlementing the behavior.

how hard is rust for a javascript programmer?
There is also a library implementation of garbage collection for Rust, made by someone from the Rust core team.
-
Is this the correct way to think about Rust? Correct me if I am wrong about anything.
Yep! And I'd actually fully agree those are garbage collection, there's also a crate by Manish which does """real""" garbage collection—https://github.com/Manishearth/rust-gc

Garbage Collection Question.
I don't know that I'd say it "works" - it's never a technique I've needed to use myself, but it's the approach taken by e.g. https://github.com/Manishearth/rust-gc

Microsoft Rust intro says "Rust is known to leak memory"
Anyway, I found something recent that implements "rc" but in terms of tracing: https://github.com/Manishearth/rust-gc/ . Maybe useful for projects involving graphs of objects.
What are some alternatives?
When comparing Mesh and rust-gc you can also consider the following projects:
jemalloc
rfcs - RFCs for changes to Rust
mimalloc - mimalloc is a compact general purpose allocator with excellent performance.
unsafe-code-guidelines - Forum for discussion about what unsafe code can and can't do
snmalloc - Message passing based allocator
tokio - A runtime for writing reliable asynchronous applications with Rust. Provides I/O, networking, scheduling, timers, ...
memory - STL compatible C++ memory allocator library using a new RawAllocator concept that is similar to an Allocator but easier to use and write.
