# Mimalloc Rust
[](https://travis-ci.org/purpleprotocol/mimalloc_rust) [![Latest Version]][crates.io] [![Documentation]][docs.rs]
A drop-in global allocator wrapper around the [mimalloc](https://github.com/microsoft/mimalloc) allocator.
Mimalloc is a general purpose, performance oriented allocator built by Microsoft.
## Usage
```rust
use mimalloc::MiMalloc;
#[global_allocator]
static GLOBAL: MiMalloc = MiMalloc;
```
## Requirements
[CMake](https://cmake.org/) and a __C__ compiler are required for building
[mimalloc](https://github.com/microsoft/mimalloc) with cargo.
## Usage without secure mode
By default this library builds mimalloc in secure mode. This add guard pages,
randomized allocation, encrypted free lists, etc. The performance penalty is usually
around 10% according to [mimalloc](https://github.com/microsoft/mimalloc)
own benchmarks.
To disable secure mode, put in `Cargo.toml`:
```rust
[dependencies]
mimalloc = { version = "*", default-features = false }
```
