# baby-mimalloc
[Mimalloc](https://github.com/microsoft/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
```toml
[dependencies]
baby-mimalloc = { version = "*", features = ["mmap", "std_mutex"] }
# baby-mimalloc = { version = "*", features = ["mmap", "spin_mutex"] }
```
```rust
use baby_mimalloc::{new_mimalloc_mmap_mutex, MimallocMmapMutex};
#[global_allocator]
static ALLOCATOR: MimallocMmapMutex = new_mimalloc_mmap_mutex();
```
