Latest Version Documentation

A drop-in global allocator wrapper around the mimalloc allocator. Mimalloc is a general purpose, performance oriented allocator built by Microsoft.

Usage

use mimalloc::MiMalloc;

#[global_allocator]
static GLOBAL: MiMalloc = MiMalloc;

Requirements

A C compiler is required for building 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 own benchmarks.

To enable secure mode, put in Cargo.toml:

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