Spotting and Avoiding Heap Fragmentation in Rust Apps

1. Mesh

   1 7 1,861 8.2 C++

   A memory allocator that automatically reduces the memory footprint of C/C++ applications.

   

   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.

3. rust-gc

   2 13 1,059 5.0 Rust

   Simple tracing (mark and sweep) garbage collector for Rust

   

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

4. shifgrethor

   3 2 328 10.0 Rust

   garbage collection

   

5. json

   4 44 5,572 8.1 Rust

   Strongly typed JSON library for Rust (by serde-rs)

   

   Don't do that if you care about memory usage. In your toy program, I wouldn't be surprised if memory usage was a lot better if you used Box instead. (even if it doesn't look like it, you can handle almost all the use cases of serde_json::Value with it, often not much less convenient)
