rustix-dlmalloc

This is a port of the dlmalloc-rs crate to rustix.

The "global" feature currently depends on rustix-futex-sync, which is only supported on Linux.

Why dlmalloc?

This crate is a port of dlmalloc to Rust, and doesn't rely on C. The primary purpose of this crate is to serve as the default allocator for Rust on the wasm32-unknown-unknown target. At the time this was written the wasm target didn't support C code, so it was required to have a Rust-only solution.

This allocator is not the most performant by a longshot. It is primarily, I think, intended for being easy to port and easy to learn. I didn't dive too deep into the implementation when writing it, it's just a straight port of the C version.

It's unlikely that Rust code needs to worry/interact with this allocator in general. Most of the time you'll be manually switching to a different allocator :)
