Does anyone know what global memory allocator (rust) WASM guest use ? And recommend alternative memory allocator?

Thanks

Rust guests currently use dlmalloc. For alternatives, one that I've used is lol_alloc which has some allocators with much smaller code size.

GitHub - Craig-Macomber/lol_alloc: Like wee_alloc, but smaller since I used skinnier letters in the name.

I can't vouch for this one but there is also talc: https://github.com/SFBdragon/talc
