# 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

A __C__ compiler is required for building [mimalloc](https://github.com/microsoft/mimalloc) with cargo.

## Usage with secure mode

Using secure mode adds 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 enable secure mode, put in `Cargo.toml`:

```ini

[dependencies]

mimalloc = { version = "*", features = ["secure"] }

```
