Top 10 Rust allocator Projects

wee_alloc

The Wasm-Enabled, Elfin Allocator

Project mention: Rust + WASM + Typescript [+ React] | /r/rust | 2023-07-18

As a note, you might find some references to use wee_alloc, but it has been unmaintained for some time and shouldn't be used. I'm using the default allocator with the wasm32-wasi target and it works fine, but I don't know if that works with wasm32-unknown-unknown too; if not there's lol_alloc.

Writing Interpreters in Rust: a Guide (by rust-hosted-langs)

Project mention: I'm wanting to write my first compiler, but getting a little bit mixed up in general. | /r/Compilers | 2023-06-24

Kind of an interpreter but it does compile to bytecode and is written in rust https://github.com/rust-hosted-langs/book I thought it was a great tutorial, both for learning rust, and about compilers

mimalloc_rust

6 441 5.0 Rust

A Rust wrapper over Microsoft's MiMalloc memory allocator

Project mention: Rust std:fs slower than Python | news.ycombinator.com | 2023-11-29

> I wish Rust would switch to mimalloc or the latest tcmalloc (not the one in gperftools).
That's nonsensical. Rust uses the system allocators for compatibility, not because they're good (they were not when Rust switched away from jemalloc, and they aren't now).
If you want to use mimalloc in your rust programs, you can just set it as global allocator, that takes all of three lines: https://github.com/purpleprotocol/mimalloc_rust#usage

Project mention: Talc – A fast and flexible allocator for no_std and WebAssembly | news.ycombinator.com | 2024-02-28

Added a new issue [1] to add TLSF to the benchmarks as it's likely going to be faster in a single-threaded environment according to the rlsf crate [2].
