baby-mimalloc

Mimalloc implemented in Rust (not a binding to the C library) with only basic features.

Lock-free multi-threading, security features, and some performance enhancements are not implemented.

It can be used in no_std environments.

Features

• mmap - Provide MimallocMmap that uses mmap as OS allocator for segments.
• std_mutex - Provide MimallocMutexWrapper that wraps Mimalloc inside std::sync::Mutex and implements GlobalAlloc.
• spin_mutex - Provide MimallocMutexWrapper that wraps Mimalloc inside spin::Mutex that can be used in no_std environments.

Usage

[dependencies]
baby-mimalloc = { version = "*", features = ["mmap", "std_mutex"] }
# baby-mimalloc = { version = "*", features = ["mmap", "spin_mutex"] }

use baby_mimalloc::{new_mimalloc_mmap_mutex, MimallocMmapMutex};

#[global_allocator]
static ALLOCATOR: MimallocMmapMutex = new_mimalloc_mmap_mutex();
